Answer:
x= 12
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
Answer: 1/12
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
