Question

How do I solve this by using substitution ?Y=3x-24
5x-y=28
Solving for x and y.

Answer 1

y=3x-24

x=8+y/3 for y and x=y/5+28/5 for x

5x-y=28
x=y/5+28/5 for x and x= 8+ y/3 for y

Answer 2

Plug in y=3x-24
5x-(3x-24)=28 combine your x
2x+24=28
Subtract2x=4
Divide x=2
Plugin to y equation
Y= 3(2)-24
Y=-18
