Question

I really need some help!

Answer 1

-4x = y + 3
y = -4x - 3

The second equation is solved for y.
We'll leave it like that.
Now we solve the first equation for y.

-4x = y + 3

-4x - 3 = y

y = -4x - 3

Write the new form of the first equation followed by the original second equation.

y = -4x - 3
y = -4x - 3

Before we get to the addition method, we see that both equations are the same.

The solution is every real number.
