Question

Solve -2 ( 3- m )+ 15 = 6m - 4 ( m - 20 ) Please show all of your work

Answer 1

ok so use PEMDAS for this one.

distribute -2 on left side to 3-m:

-6+m+15=6m-4(m-20)
9+m=6m-4m+80 Distribute the -4 and add -6 and 15.
9+m=2m+80 I think you can solve from here.

Answer 2

thank you

Answer 3

np.

Answer 4

it cant add up to 80

Answer 5

What do you mean? you need to solve for m.

Answer 6

i got 9 = 80

Answer 7

No you need to find m. So:

9+m=2m+80
9-m=80 Subtract 2m from both sides.
-m=71 Subtract 9 from both sides
m=-71 Divide by -1.

Answer 8

-71divide by -1 = 71
so m= 71

Answer 9

no.
-m=positive 71.
So 71/-1 is -71.

Answer 10

oh ok so the - become +

Answer 11

yea.
