Answer:

Answer: 1/12

Step-by-step explanation:

2/5x-4=8-3/5x.

We want to tank x out of the denominator by multiplying x on both sides.

2/5-4x=8x-3/5

Now we simplify

-12x=-1

x=1/12

Put x in the equation to check it

Answer:

x= 12

Step-by-step explanation:

2x-20=40-3x  multiply both sides of the equation by 5

2x+3x= 40+20 move the terms

5x= 40+20 collect like terms

5x = 60 add the numbers

5x= 60 divide both sides by 5

x=12
