Change these equations into the equations of linear functions.

Draw function graphs and read coordinates of the intersection.
Answer:
(12,0), (3, -1) (0,-4/3)
Step-by-step explanation:
To do this problem, you have to plug in the x and y values. For example, the first one would be 12-9(0)=12, and so on.

After rounding off, Answer is 6.

It is a linear simple equation for one unknown, lets solve it!
-4.2x + 31.5 = -65.1
we can easily get rid of decimals if we multiply the whole equation times 10:
<span>-42x + 315 = -651
</span>-42x = -651 - 315 = -966
x = 966/42
x = 23
that is the solution
