11-68.

Solve each system of equations below. Write the solution in the form $\left(x,y\right)$. Show all work.

1. \begin{aligned}[t] y + 3x = 14 \\ y - 3x =6 \phantom{0} \end{aligned}

Use the elimination method to solve for $y$.
Then use substitution to solve for $x$.
Be sure to put your answer in $(x, y)$ form.

$\left(\frac{4}{3},10\right)$

1. \begin{aligned}[t] y = 6 - 3x \\ 2x + y = 7 \end{aligned}

Use the substitution method.
