Step-by-step explanation:

Simplifying

3(2x + -1) = 4x + 15

Reorder the terms:

3(-1 + 2x) = 4x + 15

(-1 * 3 + 2x * 3) = 4x + 15

(-3 + 6x) = 4x + 15

Reorder the terms:

-3 + 6x = 15 + 4x

Solving

-3 + 6x = 15 + 4x

Solving for variable 'x'.

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

Add '-4x' to each side of the equation.

-3 + 6x + -4x = 15 + 4x + -4x

Combine like terms: 6x + -4x = 2x

-3 + 2x = 15 + 4x + -4x

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

-3 + 2x = 15 + 0

-3 + 2x = 15

Add '3' to each side of the equation.

-3 + 3 + 2x = 15 + 3

Combine like terms: -3 + 3 = 0

0 + 2x = 15 + 3

2x = 15 + 3

Combine like terms: 15 + 3 = 18

2x = 18

Divide each side by '2'.

x = 9

Simplifying

x = 9
