x = - 2/7
Step-by-step explanation:
3 (3 + 2) + 2 (x + 1) = - 5 (x - 3)
Combine like terms
3 (3 + 2) + 2 (x + 1) = - 5 (x - 3)
3 (5) + 2 (x + 1) = - 5 (x - 3)
15 + 2 (x + 1) = - 5 (x - 3)
Distribute
15 + 2x+2 = - 5x + 15
Combine like terms
2x+17 = - 5x+15
Add 5x to each side
2x+5x + 17 = - 5x+5x + 15
7x + 17 = 15
Subtract 17 from each side
7x+17-17 = 15-17
7x = - 2
Divide each side by 7
7x/7 = - 2/7
x = - 2/7
