Answer:
x= 2
Explanation:
20/x + 10/x - 10= 10/3
add 10 from both sides of the equation
20/x+10/x = 10/3 + 10
add the fraction on the left
20/x + 10/x = 40/3
3x is the common denominator
3x ( 20/x) + 3x ( 10/3) = 40/3( 3x)
simplify
60 + 10x = 40 x
group like terms
60 = 40x - 10 x
60 = 30 x
divide both sides of the equation by 30
60/30 = 30 x/ 30
2 = x
