1) distribute
2) combine like terms
3) get all variables on one side
4) get contsants to the other side
5) find x
First, get the radical by itself. Then, square both sides of the equation. Then just solve the rest.
-85-6x=91+2x
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".
You solve an inequality the same way you solve an equality. You add and subtract, multiply and divide, both sides by the same value in order to isolate one of the variables. The only extra thing you need to remember is that if you multiply or divide by a negative number, you must reverse the order of the inequality, i.e. less than or equal becomes greater than or equal.
You try to bring all instances of the variable to one side. Here is an example:5x + 5 = 3x - 2 Subtracting 3x on both sides: 2x + 5 = -2 Subtracting 5 on both sides: 2x = -7
A calculator can be used to proportions to answer a equation. This is easier to solve when having variables on both sides.
First, get the radical by itself. Then, square both sides of the equation. Then just solve the rest.
You first have to get rid of the numbers that don't have variables. then you divide by the variable and solve for it.

The variables may have different values.

To solve the equation 9x + y = 22, you need to isolate one of the variables. You can do this by either substituting a value for one variable and solving for the other, or by rearranging the equation to solve for one variable in terms of the other. For example, if you choose to solve for y, you would subtract 9x from both sides to get y = 22 - 9x. If you choose to solve for x, you would subtract y from both sides to get 9x = 22 - y, then divide by 9 to solve for x.
First get all the p variables on one side of the equation by subtracting 6p from both sides. Giving you 3p + 14 = 23 Now subtract 14 from both sides. 3p = 9 Finally divide both sides by 3. p = 3
you cannot solve this without more information. When 3 variables are involved, you need 2 equations to solve for the answers for both variables.
Where both sides are equal. It could be as simple as a fraction such as 2/3 = 4/6. It could get more complex until you end up with variables of x and y with fractional components where you have to solve for the variables. 2 + 3 = 4+ 1.
