The value of x which satisfies the equation10(x + 6) + 8(x - 3) = 5(5x - 4)also satisfies the equation
- A.
5(x - 3) = x + 5
- B.
3(3x - 5) = 2x + 1
- C.
2(x + 3) = 5(x - 5) + 4

Show answer & explanation
Correct answer: D
Solve 10(x + 6) + 8(x - 3) = 5(5x - 4): 18x + 36 = 25x - 20, so x = 8. Substituting x = 8, only 5(x - 5) = 2(x - 3) + 5 gives 15 = 15.
