Answer:

It is m = -16.

Explanation:

-7 (1 - 4m) = 13 (2m - 3)

-7 + 28m = 26m -39

2m - 7 = -39

2m = - 32

m = -16

Answer:

m = -16

Explanation:

-7(1 - 4m) = 13(2m - 3)

Distribute -7 into (1 - 4m), and distribute 13 into (2m - 3):

-7(1 - 4m) = 13(2m - 3)

-7 + 28m = 26m - 39

Add 7 to both sides of the equation:

-7 + 28m + 7 = 26m - 39 + 7

28m = 26m - 32

Subtract 26m from both sides of the equation:

28m - 26m = 26m - 32 - 26m

2m = -32

Divide both sides by 2 to solve for m:


(2m)/(2) = (-32)/(2)

m = -16
