Question

If x=3m-4 and y=6-m, which of the following expresses y in terms of x

Answer 1

What you want to do is solve for m in whichever equation it's easier to so in, then substitute that in to the other equation. For instance:

X=3m-4

Y=6-m

Solve the 2nd equation to get m=6-y

Plug that into the first equation to get x=3(6-y)-4

X=18-3y-4

X-14=-3y

14-x=3y

Y=(14-x)/3
