Explanation:

Answer 2

`\underline{+\left\{\begin{array}{ccc}5x-2y=14\\3x+2y=18\end{array}\right}\ \ \ |\text{add both sides of equations}\\.\ \ \ \ \ 8x=32\ \ \ |:8\\.\ \ \ \ \ \ x=4\\\text{substitute the value for x into either equation and solve for y}\\\\3(4)+2y=18\\12+2y=18\ \ \ |-12\\2y=6\ \ \ \ |:2\\y=3\\\\\text{Answer:}\ (4,\ 3)`
