Answer:

x = -23

Explanation:

-2/5(x+3)=8

-2/5 * (x+3) = 8

-2(x+3)/5 = 8

5 * (-2(x+3)/5) = 5 * 8 ==> multiply by 5 to remove denominator

-2(x+3) = 40 ==> simplify

-2(x+3)/(-2) = 40/(-2) ==> divide by -2 to isolate x

x+3 = -20 ==> simplify

x+3-3 = -20-3 ==> subtract by 3 on both sides to isolate x

x = -23
