@TayTay1213 : I am saying 1 interger is x. If they are consecutive, the next term must be x+1

I am just saying that the interger we are trying to find is x.

I get it so would it be like
17+(17+1)=35
so x would equal 17

But we are trying to find x. We aren't given what x is.

The idea is that if you don't know what something is you say it's equal to x.

so we don't know what the integer is so we say it's equal to x. Do you follow?

yeah but how do you right that out

Let one of the integers be= x

Dido525

That means the other integer must be = x+1
They are consecutive, meaning they come after one another.

Together those two must add to 35.

so would it be like
x+(x+1)=35
and x=17

from that equation you have to rearrange it to make x the subject

can someone show me how to write it out

the equation can be written as x+x+1=35
then simplify from there

So you get 2x+1 = 35
34=2x
