To solve for x, you need to isolate/get the variable "x" by itself in the equation.
5x + 5 = 3x + 4 Subtract 3x on both sides to get "x" on one side of the equation
5x + 5 - 3x = 3x + 4 - 3x
2x + 5 = 4 Subtract 5 on both sides
2x + 5 - 5 = 4 - 5
2x = -1 Divide by 2 on both sides to get "x" by itself
[tex]\frac{2x}{2} =\frac{-1}{2} [/tex]
[tex]x = -\frac{1}{2} [/tex]
