Question 1056573
First you want to combine the like terms "-10" and "-8".

You will then end up with this: 2c+9=5c-18.

Then, we need to move the variable to one side.

Subtract "2c" from both sides of the equation.

You will then end up with this: 9=3c-18.

Then, we need to get the variable by itself.

To do this, you add "18" to both sides of the equation.

You will then end up with this: 27=3c

You can then turn the equation around to have this: 3c=27

Then, we need to divide both sides of the equation by "3" to get the "c" by itself and ultimately solve the equation.

After the division, you should have this: c=9

c=9 is your answer.
