x + 4 = 15
- 4 -4
x = 11
You would subtract 4 because you need to isolate the x to get the value of x. You would subtract it to both sides because whatever you do on one side, you have to do it to the other side.
2 2/3 x 3/11
= 8/4 x 3/11
= 24/44
Simplified
6/11
Nobody wants to do these because, I don't know why.
None of them are correct.
