Thank you to anyone who can Help with these 3! Also I am new to this webiste so please dont mind any mistakes:)

First one Step C is incorrect because you do not 'switch' the x and y's in the equation.....

you change x to y and y to x

so step C should be x = -y+3

Second one Step E is incorrect.... '11' needs to be divided by '6' also.....not just 'x'

Third one Step E is incorrect Can YOU see why????

NOT FOR MATH 100%

how do u tell sum ur well happy
