Solve by substition: y=3x+14 y=-4x

Hey there!
This is a pretty convienient problem because we already have the value of y!
We can simply plug it in the other equation to find x and then plug it back in for y.
We have:

-4x = 3x + 14
Subtract 3x:

-7x = 14
To isolate x, divide both sides by -7

x = -2

Now, plug it back in to the y = -4x to find the value of y.

y = -4(-2)
y = 8

Now, let's check our answer.

8 = 3(-2) + 14
8 = -6 + 14
8 = 8

Therefore, our answer is (-2, 8).

Hope this helps!
