Answer:

x=-7, y=-25

Step-by-step explanation:

I will name your equations as follows:

  1. у + 4 = 3х
  2. — 2х + 5 = 19

Start with equation 2 and solve for x. This is a two-step equation.

[tex]-2x+5=19\\-2x=14\\x=-7[/tex]

Then, plug in your solution to equation 1:

[tex]y+4=3(-7)\\y+4=-21\\y=-25[/tex]
