Question 186119: y=5x+6 over 7x-3 for x

You can put this solution on YOUR website!
y = %285x%2B6%29%2F%287x-3%29 for x
:
%285x%2B6%29%2F%287x-3%29 = y
Multiply both sides by (7x-3)
5x + 6 = y(7x - 3)
:
5x + 6 = 7xy - 3y
:
5x - 7xy = -3y - 6
:
x(5-7y) = -3y - 6
:
x = %28-3y+-+6%29%2F%285-7y%29
Also can be written:
x = %283y+%2B+6%29%2F%287y+-+5%29 (Multiplied by -1/-1)
