That depends a lot on the type of equation. A common method, that works for many of the simpler equations, is to do one or more operations to isolate the variable you want to solve for on the left side. The basic principles are (1) whatever you do on one side of the equation, you have to do on the other side as well; (2) choose your operations so as to get rid of anything that is not the variable. Often this involves using inverse operations. As an example, solve:
2x + 3 = 15
The idea is to isolate the "x" on the left. First, to get rid of the "+3", do the inverse operation - subtract 3 on both sides. The result is:
2x = 12
Next you want to get rid of the "2". Since there is a multiplication, you do the inverse operation - divide by 2. The result is:
x = 6

What does SOLVE stand for in math?
"Solve an equation" means "find out, for which values of the variable or variables is the equation true".
How do you solve a equation using unknown variables?
You don't use unknown variables to solve an equation. The purpose of solving an equation is to find the value of the variable so that it's no longer unknown.
How do you solve the equation y plus 3 equals 5x?
You need another equation to make this a linear equation so you can solve for both variables. One equation with two variables is not enough to determine the correct answer.
Why do you isolate variables for math?
You isolate variables in math because the point of an equation is to solve for the variables. By isolating the variables you have learned what that variable stands for and thus solved the equation.
How can you find a variable in math?
You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables. Then you solve the equation(s), using algebra.You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables.

How do you solve variables on both sides equation using integer rules?
You first have to get rid of the numbers that don't have variables. then you divide by the variable and solve for it.
What does solve an equation of two variables given a domain?
2+2
How do you solve word problems using variables?
Use a variable to represent the unknown. 'Translate' the words to math symbols and write an equation to solve. Solve the equation. Check.
How can you use proportions to solve equations with variables on both sides?
A calculator can be used to proportions to answer a equation. This is easier to solve when having variables on both sides.
