X-3y=1 and 7x+2y=7 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?

I would solve for x in the first equation.  X in the first equation has a coefficient of 1, unlike y in the second equation which has a coefficient of 2.  I do not have to divide to solve for my variable.

Step-by-step explanation:

I would solve for x in the first equation.  X in the first equation has a coefficient of 1, unlike y in the second equation which has a coefficient of 2.

x-3y =1

Add 3y to each side

x = 1+3y

Then substitute this into the second equation.

Max would have to subtract 7x from each side and then divide by 2

7x+2y =7

2y = -7x+7

y = -7x/2 + 7/2

This makes the math complicated when it is substituted into the first equation because we are multiplying by 3.  We will have fractions.

i dont know if you cant find a way its best to actually add all of them start from 105 tho
