Answer:
x = -(91)/(2)

Explanation:

If you have any questions, feel free to ask :)

Step 1: Add
2 to both sides.


-182 + 2 = 2(1 + 2x)

Step 2: Simplify
-182 + 2 to
-180.


-180 = 2(1 + 2x)

Step 3: Divide both sides by
2.


-(180)/(2) = 1 + 2x

Step 4: Simplify
(180)/(2) to
90.


-90 = 1 + 2x

Step 5: Subtract
1 from both sides.


-90 - 1 = 2x

Step 6: Simplify
-90 - 1 to
-91.


-91 = 2x

Step 7: Divide both sides by
2.


-(91)/(2) = x

Step 8: Switch sides.


x = -(91)/(2)

~I hope I helped you :)~

-182=2(1+2x)-2

2*1=2
2*2x=4x

-182=4x+2-2
-182=4x
-45.5=x
