Answer 1

Step-by-step explanation:

$15x + 3(2x - 2) = 6(3x + 1) \\ 15x + 6x - 6 = 18x + 6 \\ 21x - 18x = 12 \\ 3x = 12 \\ x = 4$

Answer 2

Step-by-step explanation:

$15x + 3(2x - 2) = 6(3x + 1) \\ 15x + 6x - 6 = 18x + 6 \\ 21x - 6 = 18x + 6 \\ 21x - 18x = 6 + 6 \\ 3x = 12 \\ x = \frac{12}{3 } \\ x = 4$
