I need help with this problem!!

The first one is r=5

The second one is m=175

1. r=5  2.m=175

HOPE THIS HELPS :)

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

7r+10=45

Step 2: Subtract 10 from both sides.

7r+10−10=45−10

7r=35

Step 3: Divide both sides by 7.

7r /7 = 35 /7

r=5

Step 1: Simplify both sides of the equation.

m /5 −9=26

1 /5 m+−9=26

1 /5 m−9=26

Step 2: Add 9 to both sides.

1 /5 m−9+9=26+9

1 /5 m=35

Step 3: Multiply both sides by 5.

5*( 1 /5 m)=(5)*(35)

m=175

2,600 divided by 80 = 32.5
