Rachel had to complete 43 pages of math homework. If she had to complete 43 more pages of math homework than reading homework How many pages did she have to complete in all?
1. Rachel had to complete 43 pages of math homework.
2. If she had to complete 43 more pages of math homework than reading homework...
3. How many pages did she have to complete in all?

This is a word problem, so we'll need to do some math to solve it. We're given that Rachel had to complete 43 pages of math homework, and we're asked to find out how many pages of homework she had to complete in all. 

We can set up an equation to solve this problem. We'll let x represent the number of pages of reading homework Rachel had to complete. So, if x = the number of pages of reading homework, then we know that x + 43 = the number of pages of math homework. 

Now we just need to add these two equations together to find out how many pages of homework Rachel had to complete in all. 

x + x + 43 = the number of pages of homework Rachel had to complete in all

2x + 43 = the number of pages of homework Rachel had to complete in all

We can solve for x by subtracting 43 from each side of the equation. 

2x + 43 - 43 = the
