Need help solving this equation using substitution

Question

-5x+y=-1

Y-4x=-3

Answer 1

Greetings! Lets solve this shall we ?!

We begin with

-5x+y=-1

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

-------------------------------------

-5x + y = -1

y = 4x - 3 We substitute y of the second equation into y of the first equation.

--------------------------------------------------------

-5x + (4x - 3) = -1

-5x + 4x - 3 = -1

-x - 3 = -1

-x = 2

x = -2

Now, we plug -2 into y = 4x - 3 such that

y = 4(-2) - 3

y = -8 - 3

y = -11

I hope this helps!
