Clear the fraction
- 4/5(x + 2) = 4
- 5(4/5)(x + 2) = 5(4)
The distributive property
- 4(x + 2) = 20
- (4x + 8)= 20
Remove the parenthesis
- 4x - 8 = 20
Transpose 8
- 4x - 8 + 8 = 20 + 8
- 4x = 28
Divide both sides of the equatio by - 4
- 4x / - 4 = 28 / - 4
x = - 28/4
x = - 7

Assume question is:-
(- 4/5).(x + 2) = 4
(- 4).(x + 2) = 20
- 4x - 8 = 20
4x = - 28
x = - 7

multiply -4/5 into x and 2 first then solve for x
-4/5x-8/5=4
-4/5x=4+(8/5)
-4/5x=28/5
then divide by -4/5
x=-7

-4/5(x+2)=4
(-4x-8)/5=4
-4x-8=4*5
-4x=20+8
-4x=28
x=28/-4
x=-7
