Bruce bought two books . One book cost 4.00 more than three times the other together ,two books cost him 72 find prices for the two books

Sagot :

The first book: 4 + 3x
The second book: x
Overall cost: $72

We can write it as an equation:

72 = 4 + 3x + x
72 = 4 + 4x                / - 4 (both sides)
68 = 4x                      / ÷ 4 (both sides)
x = 17

Now we can check it:

The first book: 4 + 3 * 17 = 4 + 51 = $55
The second book: $17

$55 + $17 = $72, so it's correct.
