Question

What is 3x+y=-14
-2x-y=9

Answer 1

x = -5; y = 1

Explanation:

We can solve the system of equations using the elimination method.

Because y and -y cancel out, we can eliminate this variable and solve for x:

`3x+y=-14\\-2x-y=9\\\\3x-2x+y-y=-14+9\\x=-5`

Now, we can plug this x into any of the two equations to find y:

`3(-5)+y=-14\\-15+y=-14\\y=1`
