Best Answer

you treat the letters like numbers

i.e

if x=4y, rearrange for y

solution:

divide both sides by 4

therefore

y=1/4 x

example 2: 6z+x/y = 2x-y rearrange for z

solution:

multiply both sides by y: 6z+x = y(2x-y)

6z+x = 2xy-y2

Take away x from both sides: 6z = 2xy-y2-x

divide both sides by 6: z= 1/6(2xy-y2-x)

done!
