It is: 6x-5y simplified
Multiply the bottom equation by -1
3x-3y+7z
It's an expression in 'x' and 'y'.It may be simplified (cleaned up) to yield:7x + 2y - 2x + 3y =5x +5yor5 (x + y)
x = -2 and y = 1
5x + (3y-x) + (10-2y) = 5x + 3y - x + 10 -2y = 5x - x + 3y - 2y + 10 = 4x + y +10
If you mean: 5x+2y+x-3y then it is 6x-1y
5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y
(3x+2y)*(5x-3y) =3x*5x + 3x*(-3y) + 2y*5x + 2y*(-3y) [This is sometimes called the FOIL method - You multiply the First members of each bracket, then the Outers, Inners, Lasts] = 15x2 - 9xy + 10xy - 6y2 = 15x2 + xy - 6y2
It is: 6x-5y simplified
5x+2x-3y+y = (5+2)x+(-3+1)y = 7x - 2y
5x-2y+3z-2x-y-4z=3x-3y-z
Multiply the bottom equation by -1
3x-3y+7z
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
I understand this to be 4x + 3y - 5x + 2y. -x + 5y
It's an expression in 'x' and 'y'.It may be simplified (cleaned up) to yield:7x + 2y - 2x + 3y =5x +5yor5 (x + y)
