What is x and what is y in 4x-2y=4
Fed [463]

Answer:

x = 1/2y + 1

y = 2x - 2

Step-by-step explanation:

Let's solve for x.

4x−2y=4

Step 1: Add 2y to both sides.

4x−2y+2y=4+2y

4x=2y+4

Step 2: Divide both sides by 4.

4x

4

=

2y+4

4

x=

1

2

y+1

Answer:

x=

1

2

y+1

Let's solve for y.

4x−2y=4

Step 1: Add -4x to both sides.

4x−2y+−4x=4+−4x

−2y=−4x+4

Step 2: Divide both sides by -2.

−2y

−2

=

−4x+4

−2

y=2x−2

Answer:

y=2x−2

Hope this helps!
