how do you figure out this Problem?

Question

I don't understand how to simplify 2x - 2y = 2 to get y= x - 1
HELP!!!

i need Y on the left side!!!

Answer 1

2x - 2y = 2

Divide through by 2

x - y = 1

Transpose - x on both sides of the equation

x - y - x = - x + 1

- y = - x + 1

Multiply -1 on both sides of the equation

-1(- y) = -1( - x) + (- 1)(1)

- ( - y) = - ( - x) + (- 1

y = x - 1

Answer 2

2x - 2y = 2
Shift 2y to right hand side: 2x = 2 + 2y
Shift 2 to left hand side: 2x - 2 = 2y
Divide throughout by 2: x - 1 = y
Which is equivalent of y = x - 1.

Answer 3

Step 1: Divide the each term in the equation by 2 (performing any mathematical operation on both sides of an equation maintains a valid equation). This gives:
x-y=1
Step 2: Solve for y by subtracting x from both sides of the equation. This gives:
-y=1-x
Step3: multiply both sides of the equation by -1 (which changes all of the signs) This gives the final answer:
y= -1+x or x-1

Answer 4

Divide the whole problem by 2.

Divide by 2 on the left and 2 on the right.

You get x - y = 1

add y to each side -> x = y+1

subtract 1 from each side -> x-1 = y

Answer 5

2x - 2y = 1
x - y = 1 [divide both sides by 2]
x = 1 + y [add y to both sides]
x - 1 = y [subtract 1 from both sides]

Answer 6

i understand why you are confused, the steps are listed below i hope this is helping

2x - 2y = 2
subtract 2x from both sides
now you have: -2y = -2x + 2
divide the whaole equasion by -2
now you have y = x - 1

Answer 7

Sometimes you just have to try something and see how it works.

Surely you must see that every term has a 2 in it.

Divide throughout by 2.
x - y = 1
Then carry across the y
x - 1 = y
