That equation has no solution. There is no possible number that's equal to 18 more than itself.
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
23

x = -8
x = -1.2, y = -3
This cannot be solved. It needs 2 equations to solve for 2 unknowns.
-5x+50 = 25 -5x = 25-50 -5x = -25 x = 5
x=35
x = -5
