subtracting gives 4x = -12 so x = -3
72. 18*4=72
18+18+18+19+23+23+24+24=167
72 but there is such a thing as a CALCULATOR
what plus what gives me 24
subtracting gives 4x = -12 so x = -3
14 plus 4 gives us positive 18, while 0 minus 3 gives us negative three.

16 + 16 + 16 + 17 + 18 + 18 + 18 + 19 + 19 + 20 + 20 + 20 + 21 = 238
Dividing all terms by 2 gives: x2+9x+18 = (x+3)(x+6) when factored
Subtracting gives: 10x = 80 so x = 8 and y = 5
16 + 16 + 18 + 18 = 68
18 + 18 + 18 = 54
U = 4 x 18 U = 72
