1 answer:
-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.
