4-111.

Solve the systems of equations below using the method of your choice. Check your solutions, if possible. Homework Help ✎

The Substitution Method can be used to solve both of these systems.

1. $y=7−2x$
$2x+y=10$

• Substitute '7 − 2x' for y in '2x + y = 10.'

• 2x + (7 − 2x) = 10

1. $3y−1=x$
$4x−2y=16$
