Answer:
x=5, y = -3
Step-by-step explanation:
3х — 5y = 30
3х — 2y = 21
Subtract the two equation to eliminate x
3х — 5y = 30
-3х + 2y = -21
---------------------------
-3y = 9
Divide by -3
-3y/-3 = 9/-3
y = -3
Now find x
3x -2(-3) = 21
3x+6 = 21
Subtract 6 from each side
3x+6-6 = 21-6
3x= 15
Divide by 3
3x/3 = 15/3
x = 5
