Isolate the a. Note the equal sign. What you do to one side, you do to the other.

Add 5 to both sides

-5 (+5) + 1/5a = 4 (+5)

1/5a = 9

Isolate the a. Multiply 5 to both sides

(5)(1/5)a = 9(5)

a = 9 x 5

a = 45

45 is your answer for a.

hope this helps

Answer:

The answer is "1:2"

Step-by-step explanation:

Let 96 car sales are X and 96 truck sales are Y And income from 97 cars is 0.89X, income from 97 trucks is 1.07Y

$\to \frac{(0.89X+1.07Y)}{(X+Y)}=1.01\\\\\frac{X}{Y}=?\\\\\to \frac{(0.89X+1.07Y)}{(X+Y)}\ \ \text{Divide by Y and get}\ \ \frac{( \frac{0.89X}{Y}+1.07)}{(\frac{X}{Y}+1)} =1.01\\\\$

Then

$\to \frac{X}{Y}=1:2$
