Answer:
The substitution method is a technique for solving systems of linear equations. Let's walk through a couple of examples.
Step-by-step explanation:
We're asked to solve this system of equations:
\begin{aligned} 3x+y &= -3\\\\ x&=-y+3 \end{aligned}
3x+y x =−3 =−y+3
The second equation is solved for xxx, so we can substitute the expression -y+3−y+3minus, y, plus, 3 in for xxx in the first equation:
\begin{aligned} 3\blueD{x}+y &= -3\\\\ 3(\blueD{-y+3})+y&=-3\\\\ -3y+9+y&=-3\\\\ -2y&=-12\\\\ y&=6 \end{aligned}
3x+y 3(−y+3)+y −3y+9+y −2y =−3 y=−3 =−12 =6
