Answer:
3
Step-by-step explanation:
-m+8=4m-7
8=4m-(-m)-7
8=4m+m-7
8=5m-7
5m=8+7
5m=15
m=15/5
m=3
X = 7/5 is the answer to your question
To find the depreciation of the car take the amount it goes down by each year (4.1%) and make x the number of years. 34000 · (4.1% · 7) = 9758. That's your depreciation. Now just subtract the depreciation from the total and you get 24242
X+y=20
xy=99
Let a+b be denoted a,b
20 = 1,19 2,18 3,17 4,16 5,15, 6,14 7,13 8,12 (9,11) ..Stop
99=3^2*11
Thus the ages are 11 and 9 with a difference of 2.
