Question

lee has 3 packs of paintbrushes. after nancy gives him 8 more paintbrushes, he has a total of 26 paintbrushes. find a solution to the equation. the diagram shows a bar divided into four parts: three parts labeled x and one part labeled 8, with the total length labeled 26. the equation is 3x + 8 = 26. find x and state how many paintbrushes each pack contains.

Explanation:

Step1: Subtract 8 from both sides

$3x + 8 - 8 = 26 - 8$
$3x = 18$

Step2: Divide by 3 on both sides

$\frac{3x}{3} = \frac{18}{3}$
$x = 6$

Answer:

$x = 6$
Each pack contains 6 paintbrushes.
