Answer with explanation:

1. →4=q +13

Subtracting 13 from both sides

→ q+13-13=4-13

→q= -9

2.→ 5.5 = -2 +d

Adding ,2 on both sides

→ 5.5 +2=d

→d =7.5

3.→ -7 y =28

Dividing both sides by , -7 we get

→ y= -4


4. \rightarrow -13 =(m)/(-5)\\\\\rightarrow m= -13 * -5\\\\\rightarrow m=65


5. \rightarrow (3 x)/(4)=9\\\\ \rightarrow x=(4 * 9)/(3)\\\\ \rightarrow x=4 * 3\\\\ \rightarrow x=12\\\\6. \rightarrow (3p)/(8)=9\\\\ \rightarrow p=(8 * 9)/(3)\\\\ \rightarrow p =(72)/(3)\\\\p=24
