2x+y

x=2/7 y=5/6

To find the value of the expression 2x + y when x = 2/7 and y = 5/6, we substitute the given values of x and y into the expression.

Substituting x = 2/7 and y = 5/6, we have:

2(2/7) + (5/6)

Now, let's simplify the expression:

4/7 + 5/6

To add these fractions, we need to find a common denominator:

The least common multiple (LCM) of 7 and 6 is 42, so we'll convert the fractions to have a denominator of 42:

(4/7) x (6/6) + (5/6) x (7/7)

= 24/42 + 35/42

Now, we can add the fractions:

(24 + 35)/42

= 59/42

Therefore, the value of the expression 2x + y, when x = 2/7 and y = 5/6, is 59/42.
