Question

use the substitution method to solve the linear system y = x +2 2x + y =8

Answer 1

We will use the substitution method to solve this system of linear equations.

$\begin{gathered} y=x+2 \\ 2x+y=8 \end{gathered}$

The first equation is entirely in terms of x I mean, y is singled out, so in the second equation, we can substitute this for y (hence the name substitution).
