Something - 10 = 90 divided 3

Something - 10 = 90 divided 3

something - 10 = 30

something = 30 + 10

something = 40

You can also write this as the following:

x-10=90/3

then you can solve it

x-10=30

then you solve this equation

so you add 10 to both sides because you have to do the inverse operation

then you would end up with x=40

you can also check this to see if your answer is right

you plug in 40 for x

you would have something similar to this

40-10=90/3

30=30

so 40 is right

40 is the final answer
