Final answer:
The equation given in the question appears to be a typo as it does not express y varying inversely as x. A corrected version of an inverse variation problem would require the constant of variation, k, to determine the value of y when x is 11.
Step-by-step explanation:
The question provided seems to contain a typo. The correct interpretation of an inverse variation would be y varies inversely as x, which can be written as y = k/x, where k is the constant of variation. However, the provided equation x - 5x = 3 is not the equation that expresses y varying inversely as x; instead it simplifies to -4x = 3, which does not involve y and does not represent inverse variation.
If we were to correct the question to state y varies inversely as x and find y when x is 11, we would need the correct form of the inverse variation equation and the constant of variation k to solve for y.
With the corrected understanding of an inverse variation, if k was known, the formula would be y = k / 11 to find the value of y when x is 11. Without the constant k, we cannot determine the value of y.
