7-51.

Solve the equations below for the indicated variable. Homework Help ✎

6

*x*− 3*y*= 12 for*y**y*= −2*x*+ 4 for*x*4 − 2(3

*x*+ 2) = 4*x*− 10 for*x*= for

*x*

Solve for the variable by isolating it on one side.

−3*y* = 12 − 6*x*

Now divide both sides by −3.

Follow the steps outlined in part (a).

First distribute to remove the parenthesis, then combine like terms. To finish, follow steps in part (a).

*x* = 1

Multiply by a common denominator to remove the fractions. Then follow the steps in part (a).
