The given equation is:
20x + 24y = 1220
To solve this equation, we can use a variety of methods such as substitution, elimination, or graphing. However, it seems that the equation is repeated multiple times, which might be a typo or error in the question.
If we assume that the equation is only meant to be written once, we can simplify the problem to:
20x + 24y = 1220
In this case, we have a linear equation with two variables, x and y. To solve for these variables, we need either another equation or more information.
If you have any additional information or another equation related to this problem, please provide it so that I can assist you further in solving the system of equations.
