Answer 2

what do you think?

Answer 3

Its like saying .. Think of a number. divide it by 2 and add 5. It will equal 9

So we have to work backwards right? so what will you do first?

Answer 4

first you have to ssubtract 5 from both sides.

x/2+5-5=9-5

x/2=4

now multiply both sides by 2 : x/2*2=4*2 x=?

Answer 5

the first one

Answer 6

>the first one

Not correct. If you multiply both sides by 2 first, then there will be no 5 to add to both sides.
