Answer:
0
Step-by-step explanation:
Since there is no negative sign with x, you could just take out the absolute signs.
So after you take them out you have:
x+1+x+2=3
Now, combine like terms:
x+x=2x
1+2=3
Combine into an equation:
2x+3=3
Subtract 3 on both sides:
2x+3-3=3-3
2x=0
Divide 2 on both sides:
x=0
(It would be undefined if it was [tex]\frac{x}{0}[/tex])
But because it is [tex]\frac{0}{2}[/tex], it would just be 0.
Hope this helped!
Answer: x=0 or -3
Step-by-step explanation: those two lines are absolute value, which is the distance a number is away from zero so it is always positive and since 1+2=3 x is zero
It can also be -3 because l -3+1 l = l-2 l = 2 and l-3+2 l = l-1 l = 1 and 2+1+3
