I’ve had this question before, it’s C
Answer:
y=21 X=39
Step-by-step explanation:
expand brackets on first equation: 2x+2y=120
now divide the second equation by 2 on both sides:
2x+y/3=85
then subtract the second equation from the first equation
so (2x+2y) - (2x+y/3)
the 2x on both sides cancel out and you get 5/3 y
this is equal to the sum of the first equation subtract the second equation which is 35
divide both sides by 5/3 and you get
y=21
substitute y in the first equation and you get X=39
