First example:
Subtract the 8n on both sides to get the variable on one side of the equation. Do the same for the regular numbers. Then divide by -3.
This should be your final answer.
Second Example:
Do the same thing as explained in Example 1. Here's some work to help guide you.
That should be your final answer here.
Third Example:
Hope this helps and its understandable! Let me know if you still don't understand.
In any rectangle, the area is given by the product of the width and the length.
Since in this case both dimensions are represented by the correspondent function, you need to multiply the function:
Answer:
9x
Step-by-step explanation:
Since you are subtracting a negative from a positive you would get 9
7x - 1 = 5x - 8
Minus 5x on each side
2x -1 = -8
Plus 1 on each side
2x = -7
Divide by 2 on each side
x = -7/2
The number is most likely -7/2
Answer:
Step-by-step explanation:
-5(10x^2 - 9)
