Answer:

x = -5/2

Step-by-step explanation:

4x+2 = -8

We are solving for x

The first step in isolating x is to subtract 2 from each side

4x+2-2 = -8-2

4x = -10

Divide each side by 4

4x/4 = -10/4

x = -10/4

Simplify the fraction

x = -5/2

A family has annual loan payments equal to 30% of their annual income. During the year, their loan payments total $15,680. What

soldier1979 [14.2K]

First, set up a ratio: $\frac{30}{100} = \frac{15,680}{x}$
The first fraction is the percentage (30% and $\frac{30}{100}$ are the same thing) and the second is the loan payment (which is equal to the 30 in the first fraction) over their annual income ( $x$ ).
First you divide $15,680 by 30, then multiply that quantity by 100. The value calculated then replaces $x$ in your second fraction: $\frac{30}{100} = \frac{15,680}{52,266.67}$
