Question

solve the equation ( 3(w + 4) + 7 = 43 ).
show each line of work as an equation.
then check your answer.

Explanation:

Step1: Subtract 7 from both sides

$3(w+4) + 7 - 7 = 43 - 7$
$3(w+4) = 36$

Step2: Divide both sides by 3

$\frac{3(w+4)}{3} = \frac{36}{3}$
$w+4 = 12$

Step3: Subtract 4 from both sides

$w+4 - 4 = 12 - 4$
$w = 8$

Answer:

$w=8$
