Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
5x + (3y-x) + (10-2y) = 5x + 3y - x + 10 -2y = 5x - x + 3y - 2y + 10 = 4x + y +10
x=2 y=7 5x+3y= 5 7 x 2 x 3 ____ _____ 10 21 21 + 10 _______ 31
5x-2y+3z-2x-y-4z=3x-3y-z

How do you add 2x plus 3y equals 18 in 5x-y equals 11
5x + 3y = 17 is in its simplest form because there are no alike terms to combine.

No.
Multiply the bottom equation by -1
If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
