Answer:
1. r=5 2.m=175
HOPE THIS HELPS :)
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
