How do you solve c + 70 + 12c = 196 - 5c

To solve the equation c + 70 + 12c = 196 - 5c, we need to simplify and combine like terms on both sides of the equation, and then isolate the variable c on one side.

Let's go step by step:

1. Begin by combining like terms on both sides of the equation.

On the left-hand side of the equation, we have c + 70 + 12c. To combine like terms, we add the c terms together and obtain 13c. So, the left-hand side simplifies to 13c + 70.

On the right-hand side of the equation, we have 196 - 5c, which does not require any further simplification.

So, the original equation now becomes: 13c + 70 = 196 - 5c.

2. To isolate the variable c, we need to get all the terms with c on one side of the equation and the constant terms on the other side.

To do this, we can add 5c to both sides of the equation.

(13c + 70) + 5c = (196 - 5c) + 5c
13c + 5c + 70 = 196 - 0c (the -5c and +5c cancel each other out)
18c + 70 = 196

3. Now, we can isolate the term with c by subtracting 70 from both sides of the equation.

(18c + 70) - 70 = 196 - 70
18c = 126

4. Finally, to solve for c, we divide both sides of the equation by 18.

18c/18 = 126/18
c = 7

Thus, the solution to the equation c + 70 + 12c = 196 - 5c is c = 7.
