Answer: 
Solving for variable x
Move all terms containing x to the left, all other terms to the right
<u>Add -2x to each side of the equation</u>
<u></u>
<u></u>
<u></u>
<u>Combine like terms: 3x + -2x = 1x
</u>
<u></u>
<u></u>
<u></u>
<u>Combine like terms: 2x + -2x = 0
</u>

<u></u>
<u>Add 61 to each side of the equation.
</u>
<u></u>
<u></u>
<u></u>
<u>Combine like terms: -61 + 61 = 0
</u>
<u></u>
<u></u>
<u></u>
<u>Combine like terms: -50 + 61 = 11
</u>
<u></u>
<u></u>
<u></u>
<u>Divide each side by 1
