Answer 2

To find the value of y when x = -2/7, we can substitute this value into the equation:

7x - y - 4 = 0

Let's substitute x = -2/7:

7(-2/7) - y - 4 = 0

Simplifying:

-2 - y - 4 = 0

Combining like terms:

-6 - y = 0

To solve for y, we isolate it on one side of the equation by adding 6 to both sides:

-6 + 6 - y = 0 + 6

Simplifying:

-y = 6

To solve for y, we multiply both sides by -1 to get rid of the negative sign:

(-1)(-y) = (-1)(6)

Simplifying:

y = -6

Therefore, when x = -2/7, y = -6.
