There can be no answer without values for x and y.
(14x-2y)+(7x-3y)+(-3x) = 14x-2y+7x-3y-3x =(14+7-3)x-(2+3)y =18x-5y
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
-x2+14x=49
14x + 11
2x2+14x
(x2 + 14x + 49) = (x + 7)2
3y +3y = 6y
14x(x + 2)
3y + 4z + 12y = 3y -3y -3y ------------------------- 4z + 12y = 0 divide everything by 4 z + 3y = 0 -3y -3y z = -3y
x2 + 14x + 48 = (x + 8)(x + 6)
14x+7y=-9
-x+3y+6x-6y=5x-3y
