Rewrite the equation 5x – 8y + 3 = 5x – 7y + 2 into general form (ax + by + c = 0).

-y +1 =0

Step-by-step explanation:

5x – 8y + 3 = 5x – 7y + 2

We need to move all the terms to the left side

Subtract 5x from each side

5x-5x – 8y + 3 = 5x-5x – 7y + 2

-8y +3 = -7y +2

Add 7y to each side

– 8y+7y + 3 = 7y – 7y + 2

-y +3 = 2

Subtract 2 from each side

-y +3-2 = 2-2

-y +1 =0
