Question

enter a value for $x$ that makes the equation $7x - 2(x + 1) + 18 = 8x - 11$ true.

Explanation:

Step1: Expand the left-hand side

$7x - 2x - 2 + 18 = 8x - 11$

Step2: Simplify like terms on left

$5x + 16 = 8x - 11$

Step3: Move x terms to one side

$16 + 11 = 8x - 5x$

Step4: Simplify both sides

$27 = 3x$

Step5: Solve for x

$x = \frac{27}{3}$

Answer:

$9$
