Answer:

x = -2/9

Explanation:

2/5 (x - 2) = 4x

2/5x - 4/5 = 4x

2/5x - 4x = 4/5

2/5x - 20/5x = 4/5

- 18/5x = 4/5

- x = 4/5 / 18/5

- x = 4/5 * 5/18

- x = 4/18

x = - 4/18

x = - 2/9

Answer:

-2/9

Explanation:

first you are going to distrubute 2/5, so 2/5 times x is 2/5x and 2/5 times -2 is -4/5

next you set up the problem with those two answers which gives you:

2/5x - 4/5 = 4x

then multiply both sides of the equation by 5: 2x-4=20x

next move the constant to the right side and chnage the sign: 2x=20x+4

then combine like terms: -18x=4

after that divide both sides of the equation by -18: -2/9

so x= -2/9
