Step-by-step explanation:
Answer:
B and D
Step-by-step explanation:
Equations with the same x- term on both sides will have no solution
A
4x - 13 = 5(x + 4) = 5x + 20
4x ≠ 5x
This equation has a solution
B
5(3 + 2x) = 10x + 4
15 + 10x = 10x + 4
10x on both sides ⇒ no solution
C
2(3 - 5x) = 8(x + 1)
6 - 10x = 8x + 8
- 10x ≠ 8x
This equation has a solution
D
9x - 6 = 3(3x - 2) = 9x - 6
9x on both sides ⇒ no solution
