Step-by-step explanation:
subtract 10x from both sides to get 7y = -10x + 80
Divide both sides by 7
y = -10/7x + 80/7
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
