Answer:
m=-5
Step-by-step explanation:
Given: -12m-8m+5=-25m-20
Combine like terms on left side: -20m+5=-25m-20
Add 25m to both sides: 5m+5=-20
Subtract 5 on both sides: 5m=-25
Divide both sides by 5: m=-5
So m=-5
Answer:
m = -5
Step-by-step explanation:
-12m-8m+5=-25m-20
Combine like terms
-20m +5 = -25m -20
Add 25m to each side
-20m+25m+5=-25m+25m-20
5m +5 = -20
Subtract 5 from each side
5m+5-5=-20-5
5m = -25
5m/5 = -25/5
m = -5
