Answer:
x = 18
Step-by-step explanation:
Given:
Finding x for which 3b = 5a:
- 3(4x - 7) = 5(2x + 3)
- 12x - 21 = 10x + 15
- 12x - 10x = 15 + 21
- 2x = 36
- x = 36/2
- x = 18
Answer:
x = 18
Step-by-step explanation:
Plug in 4x-7 for b and 2x+3 for a in 3b = 5a
3(4x-7) = 5(2x +3)
Solve for x:
12x-21 = 10x+15
2x = 36
x=18
