Solution for 8x-3=15x+18 equation:


Simplifying
8x + -3 = 15x + 18

Reorder the terms:
-3 + 8x = 15x + 18

Reorder the terms:
-3 + 8x = 18 + 15x

Solving
-3 + 8x = 18 + 15x

Solving for variable 'x'.

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

Add '-15x' to each side of the equation.
-3 + 8x + -15x = 18 + 15x + -15x

Combine like terms: 8x + -15x = -7x
-3 + -7x = 18 + 15x + -15x

Combine like terms: 15x + -15x = 0
-3 + -7x = 18 + 0
-3 + -7x = 18

Add '3' to each side of the equation.
-3 + 3 + -7x = 18 + 3

Combine like terms: -3 + 3 = 0
0 + -7x = 18 + 3
-7x = 18 + 3

Combine like terms: 18 + 3 = 21
-7x = 21

Divide each side by '-7'.
x = -3

Simplifying
x = -3
