Step-by-step explanation:

can you please put me BRAINLIEST

1) Remove parentheses.

5+−13+x+−12+6+8=−15

2) Simplify  5+-13+x+-12+6+85+−13+x+−12+6+8  to  5-13+x-12+6+85−13+x−12+6+8.

5−13+x−12+6+8=−15

3) Simplify  5-13+x-12+6+85−13+x−12+6+8  to  x-6x−6.

x−6=−15

4)Add 66 to both sides.

x=−15+6

5)Simplify  -15+6−15+6  to  -9−9.

x=−9
