I have been trying to rearrange this formula to make x the subject:
ax - b = cx + d
My (wrong) attempt at the answer was:
x = cx + d/a - b
I know that that is wrong because x still appears on the right side of the formula. The right answer is:
x = (d+b)/(a-c)
I have no idea how to arrive at that. Can anyone talk me through it step by step?
Thanks
