To solve the equation, we can start by simplifying both sides:
-2(-c-20)=-2c-20
Distribute -2 on the left side:
2c+40=-2c-20
Now, let's add 2c to both sides:
2c+2c+40=-2c+2c-20
4c+40=-20
Next, subtract 40 from both sides:
4c+40-40=-20-40
4c=-60
Now, divide both sides by 4:
(4c)/4=(-60)/4
c=-15
Therefore, the solution to the equation is c=-15. The correct choice is A. c=-15.
Solve the equation. Note if the equation is an identity or if it has no solution.
