X + y + Z = what? X = 123, y = 124, z = 1 / 125

X + y + Z = what? X = 123, y = 124, z = 1 / 125

147 1 / 12

X+y+Z=123 X=Y X=?Y=?Z=?

There are many answers. If it's a positive integer, it can be
X=Y=1,Z=121
X=Y=2,Z=119
.
X=Y=60,Z=3
X=Y=61,Z=1

12：（x-2）=3：（2x+3）．

12：（x-2）=3：（2x+3），    （x-2）×3=（2x+3）×12，          3x-6=x+32，          3x-x=...

To solve the equation, 2 (2x + 4) - 5 (x + 1) = half of 3 - (x-3) / 3 = 1 (x-1) / 2 = 1 / 3 + X - (x-1) / 2 = 2 - (x + 2) / 3
2 (2x + 4) - 5 (x + 1) = 3 is wrong. It should be 2 (3x + 4) - 5 (x + 1) = 3

2 (2x + 4) - 5 (x + 1) = 3 4x + 8-5x-5 = 3x = 0 half - (x-3) / 3 = 1 3-2 (x-3) = 63-2x + 6 = 6x = 3 / 2 (x-1) / 2 = 1 / 3 + x 3 (x-1) = 2 + 6x3x-3 = 2 + 6x3x = - 5x = - 5 / 3x - (x-1) / 2 = 2 - (x + 2) / 36x-3 (x-1) = 12-2 (x + 2) 6x-3x + 3 = 12-2x-45x = 5x = 1
