15−2x−8−3x=−x−12+4x+43

now combine all the like terms on each side.

Add -2x and -3x

subtract 15 and -8....you subtract because the sign are different

now do the same for the other side

−5x+7=−x−12+4x+43

−5x+7=3x+31

bring the x value from the right side to the left side.

−5x+7−3x=31

combine like terms on left side

−8x+7=31

now move +7 to the right side which become..

−8x=−7+31

−8x=24

we will need to single out X by dividing

$- \frac{8x}{ - 8} = \frac{24}{ - 8} = - 3$

answer: X= -3

7 seats in each row...and there are 112 seats
112/7 = 16 rows...so there are a total of 16 rows

70 people are seated.......70/7 = 10 rows are already filled

16 - 10 = 6....so there are 6 rows that r still empty
