Question

1/9(2m-16)=1/3(2m+4) how to check my solution.
i know my solution is m=-7

Answer 1

Explanation:

1/9(2m-16)=1/3(2m+4)

shift (2m-16) to the other side

1/9=1/3(2m+4-2m+16)

1/9 1/3

left-hand side 1 and right-hand side 1 cross out

then 3x3=9 so there are only 3 cause take 3 as a use

2m - 16 = 3(2m + 4)

3x2m + 3x4

2m-16=6m+12

add 16 to both sides of the equation

2m - 16 + 16 = 6m + 12 + 16

This simplifies to: 2m = 6m + 28

subtract 6m from both sides

2m-6m=6m-6m+28

-4m=28

m=28 divided by -4

m=-7
