First, get the radical by itself. Then, square both sides of the equation. Then just solve the rest.
You decide to solve for one of the variables, for example, for "y". What exactly you do would depend on how the variables are related. For example, if you have:x + y = 5 and you want to solve for "y", you subtract "x" on both sides. If you have a product, such as: xy = 10 you divide both sides by "x".
In an equation, the left side has the same value as the right side. The importance of doing the same thing to both sides is to keep the value of both sides the same so the equation does not change.
They both have variables. They both have addition, subtraction, multiplication, and division.
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.
A calculator can be used to proportions to answer a equation. This is easier to solve when having variables on both sides.
combining like terms or subtracting from both sides of the equation.
The variables may have different values.
First, get the radical by itself. Then, square both sides of the equation. Then just solve the rest.
If an equation has two variables, we'll call them (x,y), the variables can be any value as long as both sides of the equation have the same result. If the equation was x = y, then the variables could be (1,1), (2,2), (3,3),etc...
You first have to get rid of the numbers that don't have variables. then you divide by the variable and solve for it.
7X + 2 = 5X - 1 subtract 5X from both sides 2X + 2 = -1 ==============
it means the lataduide line
It is still an equation.

An example could be: 3x-2 = x-6 and so the variable x = -2
Equal quantities may be added to both sides of a linear equation.
