Question

10x+7y=80. what is y?

Answer 1

No the answer is 70 because do seven times o and then you know that 0 so but the zero at the end and do seven times one and get seven so you know it no 80 so the number it is close to is 70

Answer 2

Explanation:

subtract 10x from both sides to get 7y = -10x + 80

Divide both sides by 7

y = -10/7x + 80/7
