what is "3x−9=7y" in standard form?
The standard form is Ax + By = Cwith A being both positive and non-fractionso we are given 3x - 9 = 7ywe add the 9 to both sides3x = 7y + 9 and subtract the 7y from both sides3x - 7y = 9There you have it in standard formHope this helps ;)
Ax + By = C is standard form3x - 7y = 9
