4x/7- 6 = -20 given
4x/7 = -14.
4x = -98
x = -24.5

answer:

step-by-step explanation:

4x/7 -6 = -20                     given  

4x/7 - 6+6=-20+6             add 6 to both sides. what you do to one side you do to the other.   now combine the results.

4x/7 = -14                           multiply by 7 on both sides. that isolates 4x

7(4x/7) = -14*7                   perform the multiplication  

4x = - 98                           divide by 4. that isolates the x        

4x/4 = - 98/4                     x = - 24.5 (-98/4 = - 24.5)
