M=4+6x+2x-7
To find the opposite of -2x+7, find the opposite of each term.
M=4+8x-7
Combine 6x and 2x to get 8x.
M=-3+8x
Subtract 7 from 4 to get -3.
M=4+6x+2x-7
To find the opposite of -2x+7, find the opposite of each term.
M=4+8x-7
Combine 6x and 2x to get 8x.
M=-3+8x
Subtract 7 from 4 to get -3.
-3+8x=M
Swap sides so that all variable terms are on the left hand side.
8x=M+3
Add 3 to both sides.
\frac{8x}{8}=\frac{M+3}{8}
Divide both sides by 8.
x=\frac{M+3}{8}
Dividing by 8 undoes the multiplication by 8.
