9x + 7 = 5x + -3

Reorder the terms:
7 + 9x = 5x + -3

Reorder the terms:
7 + 9x = -3 + 5x

Solving
7 + 9x = -3 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.
7 + 9x + -5x = -3 + 5x + -5x

Combine like terms: 9x + -5x = 4x
7 + 4x = -3 + 5x + -5x

Combine like terms: 5x + -5x = 0
7 + 4x = -3 + 0
7 + 4x = -3

Add '-7' to each side of the equation.
7 + -7 + 4x = -3 + -7

Combine like terms: 7 + -7 = 0
0 + 4x = -3 + -7
4x = -3 + -7

Combine like terms: -3 + -7 = -10
4x = -10

Divide each side by '4'.
x = -2.5

Simplifying
x = -2.5
