Yes. What do you get if you add 5 to both sides?

No, that isn't correct. You need to add 5 to both sides.

**SAARH.A5**)No, that isn't correct. You need to add 5 to both sides.

I’m confused...

So as you have y = x - 5.

The operation on the right is SUBTRACT. The opposite of SUBTRACT is ADD.

Therefore, the -5 goes onto the other side and becomes +5

You’ve got the 5 slightly muddled there. You’re going to need to add it not multiply like SAARH.A5 says. Don’t worry! It’s nothing to worry about

Hmmm... buy Y is just Y, so Y+5 yes? Isn’t that just 5Y? And then you have X-5, so you add 5 to -5? Oh wait isn’t that -10 because - + - = + but - + + = - right? Sooo... 5Y = X-10 or Y5 = X-10

I’m confused...

To the other
To the other side of the equals sign

Other side? So to the other side of X or to the Y?

Y + 5 and 5Y aren't the same thing. Why are you multiplying the Y by 5? You just need to do y + 5 to make x the subject in this case.

**SAARH.A5**)Y + 5 and 5Y aren't the same thing. Why are you multiplying the Y by 5? You just need to do y + 5 to make x the subject in this case.

So if I have Y = X-5 I have to make it a +5 to get X but then I have to add the +5 to the Y yes? So, not multiplication but addition so it’s a Y+5...? So I have the entire thing to

Y+5 = X.......?

I’m sorry, I struggle with maths a lot, I have dyscalculia (basically dyslexic but numbers) it makes a bit more sense now yes I thought the same thing but I guess it’s a different thing if you have 5 x let’s say y = 2 so 5 x 2 or 2 + 5...

So if I have Y = X-5 I have to make it a +5 to get X but then I have to add the +5 to the Y yes? So, not multiplication but addition so it’s a Y+5...? So I have the entire thing to

Yes, it is addition in this case. x = y + 5 is correct.

**SAARH.A5**)Yes, it is addition in this case. x = y + 5 is correct.

Also, I managed! Even though this wasn’t even my post thank you so much for all the help!

You could write it as x = Y + 5 or Y + 5 = x. Your answer is correct.
