Here is an example:
2x (2+4) +3x (5+7)the first thing that you will do is break the equations in parts so the first part you will solve is 2x (2+4). What you will do is 2x Times 2, which is 2x. Then you will do2x times 4 which is 8x. So now you have: 2x and 8x Ok for the next part you will do the same thing but with different numbers. 3x times 5 which is 15x and 3x times 7 which is21x. So in this part you have: 15x and 21x And now you will add them up:
- First, you lay it out like this
- when you are adding up always put the numbers in order on when you solved it.
- always add at the end
- with the answer, you don’t add 17x and 29x you just right the answer like this: 17x+29
