Question

2x-y=-14
y=x+9
Solve for the system

Answer 1

Answer:

(-14, -33)

Step-by-step explanation:

Note that y = x + 9.  Substitute (x + 9) for y in the first equation, obtaining:

2x - (x + 9) = -14, or

x + 19 = -14, or x = -33.

Now substitute -33 for x in the second equation and find y:

y = (-33) + 9 = -14

The system solution is (-14, -33).
