Help maths a level

Which side does the c go on…. How do I know I mean I put it on the rhs with the t but the ms states otherwise…
And I got it wrong as I got c to be negative but ms has it as positive

You can put c on either side of the equation. If you put it in the opposite side to the MS, it will be opposite in sign. You should be able to work through to the correct final formula.

Edit: you shouldn't lose any marks for this, provided that your algebra and final formula are correct.
