Expanding Simplyfiying And Working out the letter

To Expand and Simplyify and Equation you have to times everything in the brackets by the outter number.

* EG.* 7(5m-4)+6(2m-5)

*Remeber if you get a ++=+**if you get --=+ if you get -+=- and if you get +-=-*

**35m-28+12m-30 Now you simplify them by adding the two 'First numbers' 35m+12m=47m**

**then add the second numbers -28+-30 because theres at +- you turn it into a minus so the question would be -28-30=-58 so the full answer woul be 47m-58**

Now look at these

* EG*. Now lets look at these in a different way 7(5m-4) +6(2m-5)

**FIND M ** We already know that 7(5m-4) = 35m-28 and we know that 6(2m-5) = 12m-30

To find M you put them together 35m-28=12m-30 First you would minus 12m from both sides you start on the right doesnt matter if the number is smaller or bigger. The answer would be

23m-28=-30 You would now add 28 Because you go from right to left the second step you always add or minus from the left. **Remeber you are trying to get the number to Zero on other questions you might have to add to get 0 but what ever it takes go to 0.**** **After you add 28 on both sides you would get 23m = -2…
