Chapter 4: Q 346 (page 479)

In the following exercises, solve the systems of equations by elimination.

-x+3y=82x-6y=-20

Short Answer

Expert verified

The system of equations-x+3y=82x-6y=-20has no solution.

Step by step solution

01

Step 1. Given Information

We are given a system of equations -x+3y=82x-6y=-20

The objective is to solve the equation using the elimination method.

02

Step 2. Using the elimination method

Multiply the first equation by 2and add it with the second equation

2(-x+3y)+2x-6y=2脳8+(-20)-2x+6y+2x-6y=16-200=-4

This gives us a false statement. So the given system of equations has no solution.
