<u>answer:</u>  x = 11

<u>work:</u>

3(x+4)=5(x-2)  | distribute 3 and 5 into the parentheses.

3x + 12 = 5x - 10  | subtract 5x and move it over to 3x, and solve.

-2x + 12 = -10  | subtract 12 and move it over to -10, and solve.

-2x = -22  | divide by -2.

x = 11  | final answer.

hope this helps! ❤ from peachimin

Gotcha!

3(x+4)=5(x-2)

Distributive Property

3x+12=5x-10

Subtract 5x from 3x & 12 from -10

So far, you would have: -2x=-22

Divide both sides by -2!

Answer: x=11

Hiroto spends \$68 on e-books and paperback books combined. Each e-book he buys costs $5 and each paperback book he buys costs $
alina1380 [7]

The equation that can be used to model the situation regarding the e-books and paperback is 5x + 12y = 68

The following information can be gotten from the question:

Total amount spent on e-books and paperback = $68

<em>Cost</em><em> of e-book = $5 each.</em>

<em>Cost of paperback = $12 each</em>

<em>Number of</em><em> e-books</em><em> = x</em>

<em>Number of paperbacks = y</em>

Therefore, the equation that can be used to model the situation regarding the <em>e-books </em>and <em>paperback</em> will be:

= 5(x) + 12(y) = 68

5x + 12y = 68

The equation will be 5x + 12y = 68
