The graphs look like +graph%28300%2C300%2C-160%2C20%2C+-10%2C+100%2C+abs%2810x%2B60%29%2C+abs%28x%2B90%29+%29+.

Homing in on the 2 solutions, we see that +graph%28300%2C300%2C-20%2C20%2C+-10%2C+100%2C+abs%2810x%2B60%29%2C+abs%28x%2B90%29+%29+ which show the solutions to be about x=4 and x=-14. Roughly.

So, algebraically:
10x+60 = x+90
9x = 30
x = 30/9
x = 3.333333

10x+60 = -(x+90)
10x+60 = -x-90
11x = -150
x = -150/11
x = -13.636363..
