I have been trying to figure out the answer to this question and I have tried many different ways, but according to the answer sheet I keep getting it wrong.
How would you rearrange this equation to make x the subject?
p=3(y+2x)2
I think you mean 'solve for x' ??
p = 3 ( y+2x)^2
p/3 (y+2x)2
sqrt ( p/3) - y = 2x
x = ( sqrt (p/3) -y) / 2
