Me i cant do the problem im dying halp
2x + 4y = 24 and 5x + y = 15 as the first step, he decided to solve for x in the first equation because it has a small, even number for the coefficient. jill told him there was a more efficient way. what reason can jill give for her statement? the variable y in the second equation has a coefficient of one so there will be fewer steps to the solution. the variable x in the second equation has a coefficient of 5 so it will be easy to divide 15 by 5. the variable y in the first equation is divisible by 2 so it will be the most efficient way to start. the variable y in the first equation has a larger even number. when dividing by 4, the solution will be a smaller number
