How do you solve this step by step?

nikklg [1K]

Answer:

-2/9

Step-by-step 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
