x=9
y=12
Step-by-step explanation:
you know what the value of x is in terms of the second equation
so put that value into the first equation
so
-5 (2y-15) + 4y = 3
-10y + 75 + 4y = 3
-6y + 75 = 3
-6y = - 72
y = 12 (now we have the actual value of y, just substitute this into any of the first two original functions)
x = 2 (12) - 15
x = 24 - 15
x = 9
