8-5(2x-3)=13-6x
Solve 8 - 5(2x - 3) = 13 - 6x.
- Expand: -5(2x - 3) = -10x + 15, so left side = 8 - 10x + 15 = 23 - 10x.
- So 23 - 10x = 13 - 6x.
- Bring x terms to one side: add 10x to both sides → 23 = 13 + 4x.
- Subtract 13: 10 = 4x → x = 10/4 = 5/2.
Check: x = 5/2 gives left = 8 - 5(2x - 3) = 8 - 5(2) = -2; right = 13 - 6x = 13 - 15 = -2. Works.
Answer: x = 5/2.
