Answer:
The next step would be adding -4 to the other side since it would cancel out -4
Step-by-step explanation:
-3x + 18 = 7x
3x + (-3x) + 18= 7x + 3x

18 10x
— = —
10 10
1.8 = x
<h2>T
he car is about 6.6 years old.</h2>
Step-by-step explanation:
Given : An equation for the depreciation of a car is given by
, where y = current value of the car, A = original cost, r = rate of depreciation, and t = time, in years. The value of a car is half what it originally cost. The rate of depreciation is 10%.
To find : Approximately how old is the car?
Solution :
The value of a car is half what it originally cost i.e. 
The rate of depreciation is 10% i.e. r=10%=0.1
Substitute in the equation, 


Taking log both side,




Therefore, the car is about 6.6 years old.
