The solution to the system of equations is:
Step-by-step explanation:
Given the system of equations
Multiply -x+8y=22 by 5: -5x+40y=110
so adding the equations
solve 36y = 144 for y:
divide both sides by 36
Simplify
For 5x-4y=34 plug in y=4
Add 16 to both sides
Simplify
Divide both sides by 5
Simplify
Therefore, the solution to the system of equations is:
