Question 1)
Solving for x
x−2y=6
Add 2y to both sides.
x−2y+2y=6+2y
x =2y+6
Solving for y.
x−2y=6
Add -x to both sides.
x−2y+−x=6+−x
−2y=−x+6
Divide both sides by -2
−2y / −2=−x+6 / −2
y =1/2x −3
Question 2)
Solving for x
2x−4y=10
Add 4y to both sides.
2x−4y+4y=10+4y
2x=4y+10
Divide both sides by 2.
2x/2=4y+10/2
x=2y+5
Solving for y.
2x−4y=10
Add -2x to both sides
2x−4y+−2x=10+−2x
−4y=−2x+10
Divide both sides by -4.
−4y / −4=−2x+10 / −4
y =1 / 2 x + −5 / 2
