8 plus 15 = 23

15 + 41 + 23 = 79

Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.

If A is a variable that you are solving for and the problem is A + 5 = 23 then you subtract 5 from both sides to solve for A... A + 5 - 5 = 23 - 5 Simplify... A = 18
