Answer:

x=9

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

12=x+3

Step 2: Flip the equation.

x+3=12

Step 3: Subtract 3 from both sides.

x+3−3=12−3

Find the slope and y-intercept of 3y - 4x = 39
Alexus [3.1K]
<h2>Greetings!</h2><h3>Firstly, the slope is found by rearranging the formula:</h3>

3y = 4x + 39

y = \frac{4x}{3} + \frac{39}{3}

When x is 0, y = 0(x) +  \frac{39}{3}, so the y intercept is \frac{39}{3}

<h3>Next, the slope is simply the number in front of the x, </h3>

So  \frac{4x}{3} can be rearranged to  \frac{4}{3}x, so the slope would be \frac{4}{3}.


<h2>Hope this helps!</h2>
