Answer :
so to make the equation equal to y only, or basically get y on one side by itself or isolate the variable
30x+50y-100=0
add 100 to both sides
30x+50y=100
subtract 30x form both sides
50y=100-30x
divide both sides by 50
y=2-30/50x
y=2-(3/5)x
30x+50y-100=0
add 100 to both sides
30x+50y=100
subtract 30x form both sides
50y=100-30x
divide both sides by 50
y=2-30/50x
y=2-(3/5)x
