Answer 2

Greetings!

Solve for x.

`45(15x+20)-7x=56(12x-24)+6`
Distribute the Parenthesis.

`675x+900-7x=56(12x-24)+6`

`675x+900-7x=672x-1344+6`
Combine Like Terms.

`668x+900=672x-1338`
Add 1338 to both sides.

`(668x+900)+1338=(672x-1338)+1338`
Subtract 668x from both sides.

`[(668x+900)+1338]-668x=[(672x-1338)+1338]-668x`
Simplify.

`900+1338=672x-668x`

`2238=4x`
Divide both sides by 4.

`(2238)/4=(4x)/4`
Simplify.

`559.5=x`

`x=559.5`

Hope this helps.
