The train question..

What we need to know
- .75km
- 50km/ 60mins
- 1.5min

6(x + o.75) = 6(5/6) 1.5
6x + 4.5 = 7.5
6x/6 = 3/6
x = .5km

Then you have to convert km into m

(.5)(1000) = 500m
The train is 500m
Then we did some stuff like this....
3(x + 4) = 20
First you expand the brackets..
3x + 12 = 20
Then...
3x + 12 - 12 = 20 - 12

so..

3x = 8
Then you divide both sides by the coefficient

3x/3 = 8/3
The answer is x = 8/3



The next question

4y - 8 = 15
4y - 8 +8 = 15 + 8
4 y/4 = 23/4
y = 23/4
