Since 4 is right outside the (5 - x), you need to distribute the 4. so, you do 4 • 5 (20) and 4 • -x (-4x) which ends up as 20 -4x = 32.

then you solve!
you subtract the 20 on the left side so you are only left with the -4x. since you subtracted the 20 in the left side, you have to do the same in the right. so, 32-20 is 12.

then, you are left with -4x = 12. to get the variable, x, alone, you have to divide it by -4. but, if you do this in the left, you HAVE to do it on the right too!

so, 12 divided by -4 is equal to -3.

this means x is equal to -3!!

The average speed of Joshua during that time is 2500 m/h.

Explanation:

It is given that Joshua started cycling at 5:15 pm. By 8:09 pm he has covered a distance of 7250 m.

The total time taken by Joshua from 5:15 pm to 8:09 pm is

$2 { h } 54 \text { min }=2 \mathrm{h}+\frac{54}{60} {h}$

Dividing we get,

$2 { h } 54 \text { min }=2 \mathrm{h}+0.9 {h}$

Adding, we have,

$2 { h } 54 \text { min }=2.9 {h}$

Thus, the total time taken by Joshua is $2.9 {h}$

To determine the average speed we use the formula,

$speed=\frac{distance}{time}$

where $distance=7250$ and $time=2.9$

Hence, substituting the values we have,

$speed=\frac{7250}{2.9}$

Dividing, we get,

$speed=2500$

Thus, the average speed of Joshua during that time is 2500 m/h.
