5*4+3*3 = 29
-2x plus 3y equals 1
(4, -7)
It works out that they intersect at: (4, -7)

y=8
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
2x + 3y = 29x= 4 find x 29x= 4 x = (4/29) sub x into the first part of the sum 2x + 3y = 4 2*(4/29) + 3y = 4 note * means multiply (8/29) + 3y = 4 3y = 4 - (8/29) 3y = (108/29) note 4* 29 minus 8 = 108 y = (36/29) there is probably a quicker way to do this.

5*4+3*3 = 29
-2x plus 3y equals 1
The equation for 3y + 3y = -1 is 3y + 3y = -1.
(4, -7)
It works out that they intersect at: (4, -7)
3y + 4-26 = 0 y = 7.333
