Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
9x + 9 = 135 9x = 126 x = 14
Are you for real?! Just substitute it. 17 plus 23 is 40.

x = 2
3x + 5 = 6x + 23 -3x = 18 x = -6
2x + 2 + 5x = 23 2x +5x = 23 -2 7x = 21 X = 3
63 + 20 - 60 = 23
