Question

solve for x.

(9(x + 1) = 25 + x)

• (x = 2)
• (x = 3)
• (x = 4)
• (x = 5)

Explanation:

Distribute the constant on the left side

$$ 9(x + 1) = 25 + x $$

$$ 9x + 9 = 25 + x $$

Isolate the variable terms on one side

$$ 9x - x + 9 = 25 $$

$$ 8x + 9 = 25 $$

Solve for x

$$ 8x = 25 - 9 $$

$$ 8x = 16 $$

$$ x = 2 $$

Answer:

• (A) \(x = 2\) (Correct answer)
• (B) \(x = 3\)
• (C) \(x = 4\)
• (D) \(x = 5\)
