Jerry solved the system of equations. x-3y= 1 7x+2y=7 as the first step, he decided to solve for y in the second equation because it had the smallest number as a coefficient. max told him that there was a more efficient way. what reason can max give for his statement?

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212
