34.5=4h+7c
(34.5-7c)/4=h
Put h= (34.5-7c)/4 into another equation
30.5=8h+3c
30.5=2(34.5-7c)+3c
30.5=69-14c+3c
11c=38.5
c=38.5/11
Put c=38.5/11 into one of the equations
to calculate the h.
Answer:
x + 2 is the answer I think...
Answer:
1.- He received 388 dollars in exchange.
2.-(100 x 4) - (7.00 + 5.00)
