3,150 doesn't need to be simplified. so, i guess if it were to be simplified, it would just stay the same.
Graph the line using the slope and y-intercept, or two points.
Slope:
−1/3
y-intercept:
(0, 5)
x y
0 5
15 0
Answer: 20/3
So when solving this equation first distribute our 3,we will now have 3x-15=5.
Next we will Add 15 to both sides of our equation. Now we have 3x=20.Then divide our terms,and you will have 3x/3 = 20/3
<u>This will leave you with 1x=20/3. </u>
So the X is 20/3.
Hope that helped!
