Question

5.solve for x. show your work 2(x + 4) = x + 9

Explanation:

Step1: Expand left-hand side

$2(x+4) = 2x + 8$, so equation becomes:
$2x + 8 = x + 9$

Step2: Subtract $x$ from both sides

$2x - x + 8 = x - x + 9$
$x + 8 = 9$

Step3: Subtract 8 from both sides

$x + 8 - 8 = 9 - 8$
$x = 1$

Answer:

$x=1$
