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)
