The way to solve this problem is to isolate the X on one side of the equation.

The first step is to add 5 to both sides.

x/10 - 5

+ 5= 2/5+ 5x/10 = 5 2/5

The next step will involve multiplying both sides by 10. First, it would be helpful to deal with the mixed number 5 2/5. You could change it to an improper fraction, but I think it's even easier to change it to a decimal: 5.4

x/10

x 10= 5.4x 10x = 54

x=54

One way to approach this problem is -

1st: Get the x on one side of the equation by itself. Do this by adding 5 to each side of the equation.

x/10 -5 +5 = 2/5 +5

x/10 = 2/5 +5

2nd: The next step to getting the x by itself is to multiply both sides of the equation by 10.

(x/10)(10) = (2/5)(10) + (5)(10)

x = 20/5 + 50

x = 4 + 50

x = 54

x=54

x/10-5=2/5

x/10-5+5=2/5+5

x/10=27/5

x/10*10=27/5*10

x=54

x/10 - 5 = 2/5

x/10 = (2/5) + 5

x = 10( (2/5) + 5 )

x = 54

x/10 - 5 = 2/5

+5 +5

x/10 = 5 2/5

2/5 = .4

x/10= 5.4

`10xx(x/10) =5.4 xx 10 `

x=54
