What is the anwser to this math problem -7)-3(4m-3)=71

m=-5

Step-by-step explanation:

You first do distributive property:

(-m*-1)+(-1*-7)+(-3*4m)+(-3*-3)=71

that simplifies to:

16-11m=71

Next subtract 16 on both sides and you get:

-11m=55

Then divide by -11,

m=-5

add 8+12 to get a simplified answer of 12r-20
