Answer:
(10,30)
x=10
y=30
Step-by-step explanation:
Looking at the first one we know exactly what y is equal to in terms of x so whenever we need a y in the second equation we can just replace it with 3x which means we have
-.5x+35=3x
Solve for x and get
35=3.5x
10=x
We can then plug this x value into the first equation and solve for y
y=10*3
y=30
our answer is therefore (10,30)
