Solve for x:<br> x + 3x - 19 = 17

Natasha_Volkova [10]

<h2><u>Answer:</u></h2><h2><u></u> $\boxed{\boxed{\sf{x=9}}}$ <u></u></h2><h2><u></u></h2><h2><u>Solution Steps:</u></h2>

______________________________

<h3>1.) Combine x and 3x:</h3>

$x+3x=4x$

<em> - We combine the </em> $(x)$ <em> variables because to get to the end sum of the equation, there can only be 1 variable. So to get the 1, you combine like terms. </em>

<em />

<h3>2.) Add 19 to both sides:</h3>

$-19+19=$ Cancels Out

<em></em> $17+19=36$ <em></em>

<em> - We do this to get 1 number left over. To do this you do the opposite of what you see. In this case we have a negative 19, so you add 19 on each side of the equals. </em>

<em />

<h3>3.) Divide both sides by 4:</h3>

$4x$ ÷ $4=x$

$36$ ÷ $4=9$

<em> - We do this to get x alone. To do this you do the opposite of what you see. In this case we have </em> $4(x)$ <em> which is multiplying, so you divide by 4 on each side. </em>
