Solution

To find the value of k, we can substitute the given solution (3, 2) into the equation.

The given solution is (3, 2), which means x = 3 and y = 2.

Substitute x = 3 and y = 2 into the equation 3x - ky = 5.

This gives us 33 - k2 = 5.

Simplify the left side of the equation to get 9 - 2k = 5.

Next, subtract 9 from both sides of the equation to isolate -2k on the left side. This gives us -2k = 5 - 9.

Simplify the right side to get -2k = -4.

Finally, divide both sides of the equation by -2 to solve for k. This gives us k = -4 / -2 = 2.

So, the value of k is 2.
