Answer:
-19
Step-by-step explanation:
12x - 6 + 6 = 10x - 40 + 2
12x - 10x = -40 + 2 + 6 -6
2x = -38
x = -38/2 = -19
The two truths are:
x is a negative number (x = -19)
x+5>x (if x is positive, is true; if x is negative, is also true)
The one lie is:
3x > 2x (if x is negative, the expression will be 3x < 2x)
