8-103.

Rewrite each expression with an equivalent expression. Then evaluate each expression for

*x*= 3 and*y*= 1. Homework Help ✎3

*x*(5*y*− 4)7

*y*^{2}+ 28*y*(2

*x*− 1) + (4*x*− 3)

Multiply what is within the parentheses by what lies on the outside.

15*xy* − 12*x*

Substitute in the known values.

15(3)(1) − 12(3)

9

Factor out the 7*y*.

First combine like terms to write an equivalent expression.

Then substitute in the known values.
