Answer:
x = - 1
Explanation:
5(x - 3) + 2x + 5 = 4 + 3(x - 2) - 12 ← distribute parenthesis on both sides
5x - 15 + 2x + 5 = 4 + 3x - 6 - 12 ← collect like terms on both sides
7x - 10 = 3x - 14 ( subtract 3x from both sides )
4x - 10 = - 14 ( add 10 to both sides )
4x = - 4 ( divide both sides by 4 )
x = - 1
