Assuming 0=7-3x

3x=7 (add 3x to each side)
x=7/3 (divide by 3 each side to get x)

Hope this helped

1. The question doesn't make sense;
2. This is not a homework service. Full solutions are against the forum rules.

I won’t lie, this is pretty elementary stuff. I’m assuming you’re year 9 or lower?

This is beyond the A level specification. Can't you see that?

No it’s definitely not. A level maths is 10000000 times harder than that. Trust me I do it. That is basic algebra I’m afraid. That or I’ve misunderstood the question entirely

It is the latter. You have completely misunderstood the question.

Let us break this down:
Make x the subject of 7-3x

Now I know you might think that this is ridiculously easy, but it isnt. 7-3x is not actually equal to 7-3 ( i.e. 4 )

In fact it is 7-3x where you multiply by x. I'm afraid this is as far as my understanding will go. You would have to ask a professor for the rest of the solution.

I know it’s not equal to 4. I thought it would
x=7/3

Heavens, you may be right! It is astonoshing how you have gotten the right answer. Have you considered a pHD? Your knowledge is far beyond the A-Level syllabus.

I’m guessing that’s sarcasm
