1. Can somebody help me rearrange this formula please?

I've been trying to figure this out for hours now. could anybody help out?

I have to make x the subject of the formula

7 = 3 + x

any help would be greatly appreciated because this is driving me insane

I'm not sure what you are looking for but the only thing that can be done is

x = -3 + 7
x = 4

C'mon Mikey: 3 + WHAT = 7 ? Yes, it's that simple

And that's not a "formula"; it's an equation.

4. I am looking to make x the subject so x= (something)

so you subtracted x from both sides to give 7 - x = 3?

I could figure it out if it was a simple equation like that because the answer is obviously 4. But the questionvwhich i have to answer says:
Make x the subject of the formula 7 = 3 + x

try subtracting 3

If I subtracted 3 from 7 = 3 + x it would leave me with x = 4

it can't be that easy, surely

Your terminology is odd to me. I've never heard "make x the subject." What I have heard is, "Solve for x." And yes, it's that easy.

YES it is that simple. Yer suffering of "paralysis by analysis"

x is equal to four ; x = subject, is = verb, ....

10. Thanks guys, very much appreciate your help.

I'll let you know how I get on
