Question

Solve for x. 45(15x+20)−7x=56(12x−24)+6

Answer 1

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.
