Answer: c = 3
Step-by-step explanation: First, make sure you simplify the left side of the equation by combining our <em>c terms</em> together.
So we have 9c - 6c - 2c + 5c which simplifies to 6c.
So now we have the equation 6c = 18.
To solve for <em>c</em> in this equation, we want to get <em>c</em> by itself on the left side of the equation. Since <em>c</em> is being multiplied by 6, to get <em>c</em> by itself, we need to divide by 6 on the left side of the equation. Since we divided by 6 on the left side, we must also divide by 6 on the right side.
On the left side, the 6's cancel out so we're simply left with <em>c</em>. On the right side we have 18 divided by 6 which is 3 so we have <em>c = 3</em>.
