C; she has $70 after one month and receives $40 per month
Answer:
(3,12)
Step-by-step explanation:
2x+y=18................ equn. (1)
2x+3y=42..............equn.(2)
to eliminate x, subtract equn.(2) from equn.(1)
0-2y=-24
divide via by -2
-2y/-2=-24/-2
y=12
to solve for x, put y in any equation.
from equn. (1) 2x+y=18
2x+12=18
subtract 12 from both sides
2x=6
divide via by 2
2x/2=6/2
x=3
(3,12)
X would be 0.5. Hope this helped
