Answer:
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.
Answer:
Jerry solved the system of equations.
x minus 3 y = 1. 7 x + 2 y = 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?
The variable x in the first 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 7 so it will be easy to divide 7 by 7.
The variable y in the second equation has a coefficient of 2 so it will be easy to divide the entire equation by 2.
The variable x in the second equation has the largest coefficient. When dividing by 7, the solution will be a smaller number.
correct answer is AAAAA
