What is the error in rewriting the equation?

see below

Step-by-step explanation:

2x -y = 5

Subtract 2x from each side

-2x+2x-y = -2x+5

-y = -2x+5

The y should have a negative sign in front

or

Multiply each side by -1

y = 2x-5

1d

2b

3 false

4 d

5 3200sq,ft

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200
