Question

9(x + 1) = 25 + x

x = 2
x = 3
x = 4
x = 5

Answer 1

Answer: A) x = 2

Explanation:

9(x + 1) = 25 + x
9 * x + 9 * 1 = 25 + x
9x + 9 = 25 + x (Shift +x to LHS)
9x - x + 9 = 25 (Shift +9 to RHS)
9x - x = 25 - 9
8x = 25 - 9
8x = 16 (Shift *8 to RHS)
x = 16/8
=> x = 2

Therefore, x = 2

Answer 2

2

Explanation:

9x + 9 = 25 + x

8x = 16

x = 2
