Hi,

Rewrite the following in the form Ax+By=C 

Process: 

1) all denominators = 1

2) removing parenthesis

3) doing allowable operations to achieve standard from:



1.) y =4x+9   |4x -y = -9

2.) y =4/7x-5/7 

    7y = 4x - 5     |4x-7y = 5

3.) y =3(x-4)+5  | 3x - y = 7

4.) y = 2/5(x-5)+10 

    5y = 2(x-5) + 50   |2x-5y = -40

5.) y = 7x-5+4(x-1)/2 

    2y = 14x-10 + 4(x-1)

         18x - 2y = 14

1.)
y+=4x%2B9
-4x%2By+=9

2.)
y+=%284%2F7%29x-5%2F7
-%284%2F7%29x%2By+=-5%2F7

3.)
y+=3%28x-4%29%2B5
y+=3x-12%2B5
-3x%2By+=-7
4.)
y+=+%282%2F5%29%28x-5%29%2B10
y+=+%282%2F5%29x-5%282%2F5%29%2B10
-%282%2F5%29x%2By+=+-2%2B10
-%282%2F5%29x%2By+=+8
5.)
y+=+7x-5%2B4%28x-1%29%2F2.....both sides multiply by 2
2y+=+14x-10%2B4%28x-1%29
2y+=+18x-14
-18x%2B2y+=+-14...both sides divide by 2
-9x%2By+=+-7
