Question

I need your help please I don’t understand this

Answer 1

You would replace “4” for the letter “y” so it would be 5x+7(4)=4. Then you would do 7(4) which is 28. and then you would have 5x+28=4. I hope this helps !

Answer 2

The answer is y = -5/7x + 4/7! The first step is to subtract the 5x so it’s on the other side of the equal sign. So now the equation is 7y = -5x + 4. Then divide each of them for 7
