It is: 18 plus 50 equals 68
68
16 + 16 + 18 + 18 = 68
9 + 8 + 16 + 17 + 18 = 68
-18
It is: 68*18 = 1224

9x+3y=-68 -2x+y=18 We are asked to solve with substitution so we first write y=18+2x. Let us substitute this into the first equation. 9x+3(18+2x)=-68 9x+54+6x=-68 15x=-68-54=-122 so x=-122/15 and y =18+2(-122/15)==18+-244/15=270/15-244/15=26/15 So the solution is (-122/15,26/15) which is an ordered pair.
8.00 plus 7.40 plus 68 is equal to 83.4.
248 + 80 + 68 = 396
