The number you would get is 8
how you get this answer is as followes
x is going to be your unknown number
you have to subtract 2 right? so you do:
x-2
then it says the difference is multiplied by 5 so then you multiply it by 5
5(x-2)
then you just solve for x
your end result is 30 so you put that on the other side of the equation to solve for x
5(x-2)=30
now to solve for x you have to distribute the 5 which gets rid of the parenthesis
5x-10=30
now move the 10 over by adding
step one 5x=30+10 step two 5x= 40
now you divide by 5 to get rid of the 5
step 1) 5x/5=40/5 step 2) x=8
the answer therefore is 8
