5. the first equation gives you the value of y. So plug in the value of y into the second equation:
3x+2(-x-7)=3.
Simplify: 3x-2x-14=3.
Subtract: 1x-14=3.
Add 14 to both sides: x=17.
Now you know the x value.
You plug in the x value into the first equation: y=-17-7
Solve: y=-24
Answer: 17, -24
Your answer will be A,7. All you do is plug i the numbers then solve.
