Answer:

x=9 y=12

Step-by-step explanation:

eqn 1 - x=2y-15

eqn 2- -5x+4y=3

-5(2y-15)+4y=3

-10y+75+4y-3=0

-6y+72=0

y= 12

x=2y-15

x=2(12)-15

x= 9

They gave that -5x+4y=3 and x=2y-15

Substitution,

-5(2y-15) + 4y=3
-10y + 75+ 4y=3
75-3 = 10y - 4y
6y = 72
y. = 72/6
Y= 12

Now find x

X= 2(12) - 15
X= 24 - 15
X= 9

Soo
X= 9; Y= 12
