Answer:

C. 1/4

Explanation:

I believe you meant 2x/5 instead of 2/5x

Get everything to have a common denominator.

4x/10+ 5/10 = 6/10

4x/10= 1/10

Cross Multiply

10= 40x

x = 1/4

Answer:

C. 1/4

Explanation:

2/5x + 1/2 = 3/5 it would be easier to turn them into decimals.

.4x + .5 = .6 (Subtract .5 on both sides)

.4x = .1 (divide both sides by .4)

x = .25 (turn that into a fraction to get 1/4)

x = 1/4

Hope this helps!!
