Mathematical equation with = sign where variable appears to power of 1 only
Finding the value of the variable that makes the equation true
Whatever you do to one side, you must do exactly the same to the other
Use opposite operations to undo what's done to variable
Get variable by itself on one side
a(b+c)=ab+aca(b + c) = ab + aca(b+c)=ab+ac
Variable to power of 1 only

2x=82x = 82x=8 or x+5=12x + 5 = 12x+5=12
2x−3=72x - 3 = 72x−3=7 (add then divide)
5x+2=3x−45x + 2 = 3x - 45x+2=3x−4 (variables on both sides)
Becomes +3x+3x+3x
2x+62x + 62x+6, not 2x+32x + 32x+3
