Step 1

1 of 6We need to solve the following system using substitution:

$\left\{\begin{aligned}x-9&=0.5y\\2.2x-3.1y&=-0.2\end{aligned}\right.$

To solve a system using the substitution method, solve one of the equations for a variable and then substitute it into the other equation to write a new equation. Solve the new equation and then substitute the value you found into one of the original equations to solve for the other variable.
