x-2/5=6/7

1 answer

To solve for x in the equation x - 2/5 = 6/7, you need to isolate x on one side of the equation.

First, you can add 2/5 to both sides to eliminate the -2/5 on the left side of the equation:
x - 2/5 + 2/5 = 6/7 + 2/5
x = 6/7 + 2/5

Next, you need to find a common denominator for the fractions on the right side of the equation (7 and 5) in order to add them together. The common denominator is 35:
x = (6/7)(5/5) + (2/5)(7/7)
x = 30/35 + 14/35

Now, you can add the fractions together:
x = 44/35

Thus, the solution to the equation x - 2/5 = 6/7 is x = 44/35.
