2x + 3y = 630
x + y = 245 then you want to get rid of x so in the second equation × by -2 and get -2x -2y =-490 subtract this equation from the first to get y=$140 substitute 140 in for y and get x= $105 and 2x=210 and 3y=420 210 +420=630
14 (inches) times 4 = 56 inches which would be 4.6 feet tall
Use the slope formula

and plug in the values for x and y.
