Hi, I'm Sophie and I am currently studying Economics at Exeter University. I have 2 years of past experience tutoring maths and english at a tutoring centre to a variety of ages.
I am available to tutor:
- GCSE Mathematics
- GCSE Geography
- A Level Economics
All 3 subjects I have earned high grades in myself, but more importantly I enjoy each one enormously and would love to help you with any problems you may have in them.
In a session with me, I will focus on what you want to learn or revise, I will use example questions, as well as giving you top tips that I found useful for these subjects' exams.
Of course you are also more that welcome to provide any questions you may be finding tricky, and I will endeavour to help you.
I look forward to meeting you soon!

To solve the equation: (5x+3)/(x) + x = 1, where (x) is the denominator, we have to convert the equation into an equation without any denominators.
To do this, we multiply each variable by (x), so the equation becomes: (5x+3) + (x)(x) = (1)(x).
The next step is to expand the brackets: 5x + 3 + x^2 = x
After this, we move all variables onto one side of the equation (by subtracting x from both sides) so that it equals 0: x^2 + 4x + 3 = 0
Factorsing this equation we get: (x + 3)(x + 1) = 0
Therefore, we can equate each bracket to 0, giving the solutions for x:
x + 3 = 0, x = -3
x + 1 = 0, x = -1see more
