12(m – 4) = 3m - 3?

12m - 48 = 3m - 3
9m = 45
m = 5

12(m - 4) = 3m - 3
4(m - 4) = m - 1
4m - 16 = m - 1
3m = 15
m = 5

Answer: m = 5

Proof (equality of the equation):
12(5 - 4) = 3(5) - 3
12(1) = 15 - 3
12 = 12

12(m – 4) = 3m - 3
multiply out the brackets (12 x m = 12m, and 12 x -4 = -48)
12m-48 = 3m-3
add 48 to each side (-48 + 48 = 0, and -3 + 48 = 45)
12m = 3m + 45
subtract 3m from each side (12m - 3m = 9m, and 3m - 3m = 0
9m = 45
divide both sides by 9 (9/m = m, and 45 / m = 5)
m = 5

hope u get an A ;)

Are you solving for m? Then;

12m - 48 = 3m -3

9m -48 = -3

9m = 45

m = 5

12(m - 4) = 3m - 3
12*m - 12*4 = 3m - 3
12m - 48 = 3m - 3
12m - 3m = 48 - 3
9m = 45
m = 45/9
m = 5

12(m-4) - 3M -3
12m -4*12 = 3m -3 - distributive property
12m - 3m -48 = 3m-3m -3 - move M's to one side

9m -48 = -3
9m -48 +48 = -3 +48 move constants to one side

9m =+45
9m/9 = 45/9
m = 5

12m - 48= 3m -3 no do ur own homework
