How would you solve - 7x-4y=16

So one easy way is to make the equation equal to only one place holder so

-7x-4y=16

add 7x to both sdies

-4y=16+7x

multiply both sides by - 1

4y=-16-7x

divide both sides by 4

y=-4-7/4x

subsitute values for x and get values for y

exg

if x=0 then y=-4

if x=1 then y=-5 3/7

etc
