Question

*Work must be shown* :/
Solve the system using substitution. Check your answer.

y = -2x + 8
5y - x + 4 = 0

(Simplify your answer. Type an ordered pair.)

Answer 1

First step:
From the first equation, we know \(\color{red}{y}=\color{blue}{-2x+8}\)
Put that y to replace the y of the second equation and solve for x
\(5\color{blue}{(-2x+8)}-x+4=0\)
