Question

jermey wants to buy a new computer . the saleswomen says he can make a down payment and then pay for the computer in installments

Answer 1

The correct answer is:

`y=(-x+t)/(z) \\`

Explanation:

We want to solve for the amount of money he pays each month. This is represented by y in the equation. This means we want to isolate y in the equation:

x = t - yz

We first want to subtract t from each side:

x - t = t - yz - t

x - t = -yz

Now we want to cancel the negative sign and z. We can isolate both of these at the same time; divide both sides by -z:

\frac{x-t}{-z} = \frac{-yz}{-z} \\ \\\frac{x-t}{-z}=y

We can divide the numerator by the negative sign; this gives us

\frac{-x+t}{z}=y
