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'
