Question

solve the equation. justify each step.
a8) \\( 4x + 9 = 16 - 3x \\)

Explanation:

Step1: Isolate x terms (add 3x)

$4x + 3x + 9 = 16 - 3x + 3x$
$7x + 9 = 16$

Step2: Isolate constant terms (subtract 9)

$7x + 9 - 9 = 16 - 9$
$7x = 7$

Step3: Solve for x (divide by 7)

$\frac{7x}{7} = \frac{7}{7}$
$x = 1$

Answer:

$x=1$
