4n - 3= -2n + 9
add 3n to both sides

4n= -2n +12
add 2n to both sides

6n= 12
divide both sides by 6

n= 2

Check:
4n-3=-2n+9
4(2)-3= -2(2)+9
8-3= -4+9
5=5


Hope this helps! :)

41. Tavon has a $50 gift card that loses $2 for each
DENIUS [597]

Answer:

Step-by-step explanation:

d=days not used

50-2d  =  40-1.5d

subract 40 each side

10-2d =1.5d

10= 0.5d

20=d

After 20 days the value of the gift  cards will be equal.

20*2=40      50-40=10 ($10)

20*1.5=30     40-30=10 ($10)

each card will have a value of $10  after 20 days,when both cards have equal value
