Question 415639
You can solve this by dividing -1/8 to each side of the equation:

x= (-9/10)  / (-1/8 )        divide -1/8 to each side of the equation to make the coefficient of X become 1. 
x= 36/5              when you divide a fraction, you actually multiply the reciprocal of the fraction. That is, (-9/10 )/(-1/8)=(-9/10)*(-8/1)=72/10=36/5.
