4-83.

Candice is solving this system: Homework Help ✎

 $2x−1=3y$ $5(2x−1)+y=32$
1. She notices that each equation contains the expression $2x−1$. Can she substitute $3y$ for $2x−1$? Why or why not?

Try it for yourself. Does it work?

2. Substitute $3y$ for $2x−1$ in the second equation to create one equation with one variable. Then solve for x and y.

• Remember to check your answers.

• y = 2; use this information to solve for x.
