635/72=-5/2(-11/4+x)

distribute

635/72 = -5/2 * -11/4 - 5/2x

635/72 = 55/8 -5/2 x

multiply each side by 72 to clear the fractions

72*635/72 = 72*(55/8 - 5/2 x)

distribute

635 = 72* 55/8 - 72* 5/2 x

635 = 495 - 180x

subtract 495 from each side

140 = -180 x

divide by -180

-140/180 = x

-14/18 =x

-7/9 =x
