Answer:
[tex]- 7 + \frac{2}{3}n = 13 : n = 30[/tex]
Step-by-step explanation:
[tex]-7+\frac{2}{3}n=13[/tex]
Add [tex]7[/tex] to both sides:
[tex]-7+\frac{2}{3}n+7=13+7[/tex]
Simplify:
[tex]\frac{2}{3}n=20[/tex]
Multiply both sides by [tex]3[/tex]:
[tex]3 * \frac{2}{3}n=20 * 3[/tex]
Simplify:
[tex]2n=60[/tex]
Divide both sides by [tex]2[/tex]:
[tex]\frac{2n}{2}=\frac{60}{2}[/tex]
Simplify:
[tex]n = 30[/tex]
Hope I helped. If so, may I get brainliest and a thanks?
