# Chapter 9 - Section 9.3 - Solving Pairs of Linear Equations by Substitution - Exercises: 16

There are no common solutions.

#### Work Step by Step

$2x+8y=12$ $x=-4y$ Substitute -4y for x in the first equation. $2(-4y)+8y=12\longrightarrow$ simplify $-8y+8y=12\longrightarrow$ simplify $0=12$ Since this is a false statement, there are no common solutions for the 2 equations.
