Answer:
83
Step-by-step explanation:
form 2 equations(1). 2(x+y)=22. (2)xy=24,then solve simultaneously
xy-3x=40, x=5
x(y-3)=40
y-3=(40/x)
y=(40/x)+3
y=(40/5)+3
y=8+3
y=11
let's recall the vertical line test, if a vertical line hits the graph or points twice, then is NOT a function. Check the picture below.
x=9
12+12x=3+13x then simplify
