To find the value of x in the inverse variation equation given by xy = k, where y = 4 and k = 7, we can follow a simple calculation.
1. Start with the equation:
xy = k
2. Substitute the known values of y and k:
x * 4 = 7
3. To isolate x, divide both sides of the equation by 4:
x = 7 / 4
4. Perform the division:
x = 1.75
Therefore, when y is 4 and k is 7, the value of x is 1.75.
