So first you plug 6 into the equation which is 4(6)-10.
Using PEMDAS, you solve what’s in the parenthesis first and you get 24-10.
24-10=14
f(6)=14
the number is 6
let the number be n , then the difference of this number and 3 is n - 3
4 times this is 4(n - 3) = 12 ( solve for n )
divide both sides by 4
n - 3 = 3 ( add 3 to both sides )
n = 3 + 3 = 6
the number is 6
