How do you solve this problem it just says solve x2 plus 3y equals 7 3x plus y2 equals 3?

x2 + 3y = 7

3x + y2 = 3

3y = x2 + 7

y2 = -3x + 3

y = x2/3 + 7/3

y = ± √(-3x + 3)

If you draw the graphs of y = x2/3 + 7/3 and y = ± √(-3x + 3) in a graphing calculator, you will see that they don't intersect, so that the system of the given equations has not a solution.
