Answer:

Simplified is 3x - 8

Step-by-step explanation:

First, put the like terms together, so rearrange that equation to 12x - 9x - 15 + 7. Then from there you subtract 9x from 12x which is 2x and add 7 to negative 15, which is -8.

Ten times the sum of half a number and 6 is 8.

Sedaia [141]

That would be

$10( \frac{1}{2} n + 6) = 8$
$\frac{1}{2} n+6= \frac{8}{10}$
$.5n + 6 = .8$
$.5n = -5.2$
$n=-2.6$

Hope that helps :)
