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.

mote1985 [20]

Answer:

x=16-2y

Step-by-step explanation:

\mathrm{Subtract\:}\frac{1}{4}y\mathrm{\:from\:both\:sides}

\frac{1}{8}x+\frac{1}{4}y-\frac{1}{4}y=2-\frac{1}{4}y

\mathrm{Simplify}

\frac{1}{8}x=2-\frac{1}{4}y

\mathrm{Multiply\:both\:sides\:by\:}8

8\cdot \frac{1}{8}x=8\cdot \:2-8\cdot \frac{1}{4}y

\mathrm{Simplify}

x=16-2y

Final Answer: x=16-2y
