Question

2x-y=3
SHOW WORKKKKKK

Answer 1

Well, y = 2x - 3.

Step 1:

Subtract 2x from both sides.

-y = -2x + 3.

Step 2:

Divide it all by negative 1.

y = 2x - 3.

IF YOU WANT TO SOLVE FOR X:

Well, x = .5y + 3/2

Which equals to:

(y + 3)/2.

Step 1:

Add y to both sides.

2x = y + 3.

Step 2:

Divide it all by 2:

x = .5y + 3/2

Which equals to:

(y + 3)/2.

They are the same.
