</h2><h2 /><h2><u>Solution Steps:</u></h2>
______________________________
<h3>
1.) <u>
Swap sides so that all variable terms are on the left hand side:</u></h3>
<em> - This is an optional step. I prefer the numbers to be on the left hand side, but it's not necessary.
</em>
<u>
Equation at the end of Step 1:</u>
- <u />
<h3>2.) <u>Combine 7x and 5x:</u></h3>
<em> - We combine like terms because there is 2 x's, and we need 1 x. </em>
<u>Equation at the end of Step 2:</u>
- <u />
<h3>3.) <u>Subtract 9 from both sides:</u></h3>
- Cancels Out
<em> - When solving problems like this, to get x alone you have to do the opposite of what you see.
</em>
- In this case, we have a positive 9. So to get rid of 9 we do the opposite: -9 on each side.
<u>
Equation at the end of Step 3:</u>
- <u />
<h3 /><h3>4.) <u>Divide both sides by 12:</u></h3>
- ÷
- ÷
<em> - When solving problems like this, to get x alone you have to do the opposite of what you see.
</em>
- In this case, we have 12 being multiplied by x. So to get rid of the 12 we do the opposite: Divide by 12 on each side.
