How do you solve elimination on this problem 3x 2y-31 5x 2y-49?

To solve the system of equations using elimination, first write the equations in a standard form. The equations given seem to be misformatted; if we assume they are (3x + 2y = 31) and (5x + 2y = 49), you can eliminate (2y) by subtracting the first equation from the second. This results in (2x = 18), so (x = 9). Substitute (x = 9) back into one of the original equations to find (y).
