When you are solving for y and you have an equation such as y-x4 would you do the opposite by adding x to both sides?

If you mean y - x = 4, then yes, the correct thing to do is to add "x" to both sides - assuming you want to solve the equation for "y". In general, keep the variable you want to isolate (solve for) on the left, and move everything else to the right by doing the inverse (opposite) operation. If you wanted to solve the same equation for "x", you would first subtract "y" on both sides, to get rid of the "y" on the left side. Then you would need to multiply both sides by "-1" to get rid of the minus sign on the left.

X - 9 11?
The value of X in the equation X - 9 = 11 is 20. This obtained by adding both sides of the equation with 9.
What are the steps to solving a radical equation?
Details may vary depending on the equation. Quite often, you have to square both sides of the equation, to get rid of the radical sign. It may be necessary to rearrange the equation before doing this, after doing this, or both. Squaring both sides of the equation may introduce "extraneous" roots (solutions), that is, solutions that are not part of the original equation, so you have to check each solution of the second equation, to see whether it is also a solution of the first equation.
How do you solve 10x plus 3 equals 15?
In this case, we are solving backwards to find the value of 3. We must reverse the order of operations to solve for x since we are working backwards. subtract 3 from both sides of the equation. this will leave us with 10x = 12. Then, we can divide both sides by 10, and we will be left with 12/10. The main goal of solving for x is to isolate x. We want x to be on one side of the equation all by itself. Think of equations like a balance bean. If we take 3 away from both sides, the balance will still weigh the same on both sides. Then, if we divide 10 by both sides, the balance will still weigh the same on both sides again because its done to both sides of the equation. Aside from when you are simplifying one side of the equation for simplicity, what you do to one side of the equation you must do to the other.
In general when solving a radical equation should you first isolate the radical and then both sides?
It often helps to isolate the radical, and then square both sides. Beware of extraneous solutions - the new equation may have solutions that are not part of the solutions of the original equation, so you definitely need to check any purported solutions with the original equation.
How do you solve equations with variables on both sides with fractions?
You first find a common denominator. The least common denominator is preferable but not essential. Multiply each term in the equation by this common denominator. The equation now has no fractions, only variables on both sides. If the resulting equation is linear, quadratic, cubic or exponential then there are relatively simple ways of solving them. There may be an analytical method for solving polynomials of higher order or other equations. However, whether or not there is a method will depend on the precise nature of the equation.
In algebra adding the opposite to both sides of an equation is a process better known as what?
I'm pretty sure you mean balancing an equation to solve for a particular vairable
How do you solve the equation y equals x squared?
If you are solving for y, it is fine. If you are solving for x, divide both sides by x and the equation should be x = y/x

What law is applicable in solving angle if given two sides and an angle opposite any of them?
Pythagorus' theorem
Why is it important to keep both sides of the equation equal?
If both sides of an equation are not equal, it won't be an equation any more! In solving equations, the strategy is to change both sides in the same way, so that an 'equivalent' equation is produced. An equivalent equation has the same solution as the original equation. You are aiming for an equation in which the variable is alone on one side. The quantity on the other side is the solution.
The definition of division property of equality?
I think its a property in which both sides of an equation are equal either by adding, subtracting, multiplication, or division.
What do you call the solution of a equation derived from an original equation that is not a solution of the original equation?
That's an extraneous solution. You need to check for these when algebraically solving equations, especially when you take both sides of an equation to a power.
How could you isolate the variable g in this equation g - 6 equals 12?
g - 6 = 12In order to isolate the variable 'g' you must add 6 to both sides of the equation.In algebra, you must perform the opposite operation of the one presented in the problem. For example, the equation above has "minus 6". The opposite opporation for subtraction is addition. So in this case you must ADD 6 to both sides of the equation. Performing the operation to both sides of the equation is essentially multiplying the entire equation by 1, and any time you multiply something by 1 you get the same thing. Because of this, adding to both sides of the equation does not change the final answer.So..g - 6 = 12+6 +6g = 18
How do you solve augmented matricies?
The short answer, multiply on both sides of the equation by the inverse of the matrix you need to remove. Just like solving 3x = y for x. Multiply on both sides of the equation by 1/3.
