Question

How do you solve `-348= - 4a + 8( 6a - 5)`?

Answer 1

the answer is `a=-7`

Explanation:

distribute `8` to the inside equation next to it
`-348=-4a+48a-40`
combine like terms
`-348=44a-40`
add `40`
`-308=44a`
divide `44` to both sides
`a=-7`

Answer 2

`color(blue)(a = -7`

Explanation:

`-4a + 8 (6a - 5) = -348`

`-4a + 48a - 40 = -348` Removing the bracket.

`44a = -348 + 40 = -308`

`a = - (cancel(308)^color(red)(7)) / (cancel( 44)`

`color(blue)(a = -7`
