Step 1

1 of 3Let's use method of elimination and solve the system of equations. First of all, add the equations to get an equation, which will contain only one variable and solve it.

$\begin{aligned} (4.25x - 1.28y) + (x + 1.28y) &= -9.2 + 17.6\\ 4.25x + x &= 8.4\\ 5.25x &= 8.4\\ x &= 1.6 \end{aligned}$
