Solve the system.
$\left\{ \begin{tabular}{l}$ y = x + {\color{red}-2} $\\$ y = -{\color{red}3} x + {\color{red}10} $\end{tabular} \right.$

• ALGEBRA -

The TeX makes it hard to read, but it appears you want to solve

y = x + 2
y = -3x + 10

If that's so, then just substitute the 1st value for y into the 2nd equation:

x+2 = -3x+10
4x=8
x=2
so, y=4
