Ig we hav to solve for x ? Don't take mah word for it cuz I havent dont dis in years but pwetty sure dat (8x+12)=(5x+75) cuz they're opposite of each other. Sooooo if u do dat rlly quick das 15.

MidniteSunny:

Den just plug 15 bacc into (5x+75) and subtract that from 180 (aka ENA).

Krissy525:

Ok, so you set the equations equal to each other. So 5x+57=8x+12. Subtract 8x from both sides to get -3x+57=12. Then subtract 57 from both sides. You then get -3x=-45. Divide by -3 and you get x=15

Krissy525:

So when you plug in 15 as x, you get 5(15)+57, which equals 132
