Solve each equation for the missing variable. If your answer is not an integer, write it as an improper fraction.
FromTheMoon [43]

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.

5n-14=8n+4\\ \\ 5n-8n=4+14 \\ \\ -3n=18\\ \\ n=-6

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.

-15 - 5a + 4 = -2 + 30a + 26\\ \\ -5a-30a=-2+26+15\\ \\ -35a=39\\ \\ a = \frac{39}{-35}

That should be your final answer here.

Third Example:

3 - 9x = -8x + 25\\ \\ -9x+8x=25-3\\ \\ -x=22\\ \\ x=-22

Hope this helps and its understandable! Let me know if you still don't understand.

First you have your two numbers: 1.5 and 4.
The question explains that they travel 1.5 miles 4 times each, meaning you multiply the two.
1.5×4=6

So, your answer is 6 miles.

Hope this helps!
