There are no solutions for this equation.

the l x l lines between the x means that we are using the absolute value. In short, x will always be a positive number. Because of this there are no solutions.

I'll solve anyway so you can see that it is unsolvable...

l x l + 10 = 1
subtract x from both sides
l x l = -9
l x l ≠ -9
An absolute value cannot be a negative number...
