Answer:
x = 15 5/6
Step-by-step explanation:
-4 1/4x-7 6/8x=-190
get a common denominator 8
-4 1/4*2/2 x - 7 6/8 x = -190
-4 2/8 x - 7 6/8 x = -190
combine like terms
-11 8/8 x = -190
-12x = -190
divide by -12
-12x/-12 = -190/-12
x = 190/12
divide top and bottom by 2
x = 95/6
change to an improper fraction
6 goes into 95 15 times with 5 left over
x = 15 5/6
