Oh, what a happy little math problem we have here! To get 5 using four 3's, you can add 3 + 3 to get 6, then subtract 3 ÷ 3 to get 5. Just remember, there are no mistakes, only happy little accidents in math!

4=4(3s) 4=12s s= 1/3
4
5 of them with a remainder of 1
Bring all the unknown values to one side and the known values to the other 7s - 12 = 3s - 4 Subtract 3s from both sides 7s - 3s - 12 = 4 4s - 12 = 4 Add 12 to both sides 4s = 4 + 12 4s = 16 Divide both sides by 4 s = 4
7-2s+4+5s ..... Okay first you combine like terms(add the like terms)..so its going to be 11+3s I did 7+4=11 then -2s+5s=3s So the answer can be 11+3s or 3s+11
