2x+7y=1

Solving for y

Our main aim is to keep y terms on LHS ...therfore subtract 2x both sides ... we get

2x +7y -2x =1-2x

hence we get 7y =(1-2x)

now divided by 7 both sides

we get 7y/7 =(1-2x)/7

OR solving we get

y =(1-2x)/7 answer

Solving for x

Our main aim is to keep x terms on LHS ...therfore subtract 7y both sides ... we get

2x +7y -7y=1-7y

hence we get 2x =(1-7y)

now divided by 2 both sides

we get 2x/2=(1-7y/2

x=(1-7y)/2 answer
