Hello, Let x represent the total of jumps y represent the total “ raised the roof "
Here are two equation: 3x+2y=50 x+y=19 To solve this, I would prefer to use substitution because it is the easiest way to do: x+y=19 Times 3 from both side 3x+3y=57 - 3x+2y=50 = y=7 x=19-7=12. As a result, Roxanne jumps 12 , and “ raised the roof ” 7 times. Hope it help!
