Six less than the product of 3 and a number is 4. use the variable b for the unknown number

Six less than means -6 the product of 3 and a number (3 times b) is four=4
-6+3 times b=4
pemdas
multiplication first
3 times b=3b
3b-6=4
add 6 to both sides
3x=10
divide both sides by 3
x=10/3

40%=2/550=1/230=3/1056=14/25

Ithink it is correct but just ask someone else but i am sure it it
