## maths

6y=9-3x rearrange for x= Change 6y = 9 - 3x to: 3x = -6y + 9, then solve for x by dividing both sides by 3 to get: x = -2y + 3 when you divided both sides by 3. there is a rule where you cant divide the answer if theirs an addition sign. so 3x=-6y+9

## rational functions

A rational function that passes through (0,0) and (4, 8/7) has the x-axis as a horiztonal asympotote. It also has 2 vertical asymptotes x=3, x=-3. I understand that to set it up, it is y= ax+b / (x+3)(x-3). I don't understand how to solve for a and b.
