Short Answer

Expert verified

The system of equations has no solution.

Step by step solution

01

Step 1. Given the information

The system of equations is,

y=78x+4-7x+8y=6

02

Step 2. Substituting the value y in the equation.

Substituting y=78x+4in the equation

-7x+8y=6

-7x+8(78x+4)=6

-7x+7x+32=6

-7x+7x=6-32

0=-26

The system of equations has no solution.
