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
Are you for real?! Just substitute it. 17 plus 23 is 40.

3x + 5 = 6x + 23 -3x = 18 x = -6

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

x=9
x = 12
2x + 7 + 2x = 23 4x + 7 = 23 4x = 16 x = 16/4 x = 4
