Answer:46
Step-by-step explanation:
Use BODMAS to solve this
First is to open the innermost bracket
6+(4x(5+(10÷2)))
6+(4×(5+5))
Then the next bracket
6+(4×(10)
Open the next bracket, then multiply before adding
6+40
=46
If x=3 then 5x3=15-2=13+6=19x1/4=4 3/4 so that means that 2 1/4+2 1/2 could be equivalent
P.S.I just chose 3 because it was the first number to pop into my head
