Answer:
Step-by-step explanation:
Let the number of month be x
<u>Expression to show amounts</u>
- 2350 + 200x = 3250 + 175x
- 200x - 175x = 3250 - 2350
- 25x = 900
- x = 900/25
- x = 36
<u>Amount</u>
- 2350 + 200*36 = 2350 + 7200 = 9550
Time is 36 months
Amount is $9550
3x - 4y = 12 ----- (1)
x + 4y = 20 ------ (2)
equation (2) x 3:
3x + 12y = 60 ---(2a)
(2a) - (1):
12y - (-4y) = 60 - 12
12y + 4y = 48
16y = 48
y = 3 ---- sub into equation (2)
x + 4(3) = 20
x + 12 = 20
x = 8
Ans: x = 8 and y = 3 (True)
