What is the solution to the two equations, X+7y=24, and X-9y = - 24 Can you show work?

X + 7y = 24

x - 9y = - 24. subtract bottom equation from the top

16y = 48

y = 3 divide both sides by 16

plug 3 in for y in either equation

x + 7 (3) = 24

x + 21 = 24

x = 3

solution is (3, 3)

By graphing it's 3,3
