    I've been going over changing the subject of a formula for my A-level C2 Maths and I can't work out this question:
    (x+c)/d = 2(x+e)/f
    'Make x the subject'
    Can anyone help me out?

    Multiply both sides by df, expand the brackets and rearrange and factorise again if needed to make x the subject. Hopefully that works, that's the general method I would use for most problems like this.
