26.Amelia correctly began solving the system of equations.


9x + 3y = 15
y = −3x + 5

First, she wrote the second equation in standard form. Second, she multiplied the
second equation by ─3. Then she added the first equation with the new second
equation.
What does Amelia already know about the solution of the system of equations, even if
she does not complete the next step?
A. It has infinite solutions.
B. There is no solution.
C. The value of x is 0.
D. The value of y is 0.

Answer:

9x-3y=15

9x-3y=15 [2] y=3x-5

9x-3y=15 [2] y=3x-5Equations Simplified or Rearranged :

9x-3y=15 [2] y=3x-5Equations Simplified or Rearranged : [1] 9x - 3y = 15

9x-3y=15 [2] y=3x-5Equations Simplified or Rearranged : [1] 9x - 3y = 15 [2] -3x + y = -5

9x-3y=15 [2] y=3x-5Equations Simplified or Rearranged : [1] 9x - 3y = 15 [2] -3x + y = -5Solve by Substitution :

9x-3y=15 [2] y=3x-5Equations Simplified or Rearranged : [1] 9x - 3y = 15 [2] -3x + y = -5Solve by Substitution :// Solve equation [2] for the variable y

9x-3y=15 [2] y=3x-5Equations Simplified or Rearranged : [1] 9x - 3y = 15 [2] -3x + y = -5Solve by Substitution :// Solve equation [2] for the variable y

9x-3y=15 [2] y=3x-5Equations Simplified or Rearranged : [1] 9x - 3y = 15 [2] -3x + y = -5Solve by Substitution :// Solve equation [2] for the variable y [2] y = 3x - 5

9x-3y=15 [2] y=3x-5Equations Simplified or Rearranged : [1] 9x - 3y = 15 [2] -3x + y = -5Solve by Substitution :// Solve equation [2] for the variable y [2] y = 3x - 5// Plug this in for variable y in equation [1]

9x-3y=15 [2] y=3x-5Equations Simplified or Rearranged : [1] 9x - 3y = 15 [2] -3x + y = -5Solve by Substitution :// Solve equation [2] for the variable y [2] y = 3x - 5// Plug this in for variable y in equation [1] [1] 9x - 3•(3x-5) = 15

9x-3y=15 [2] y=3x-5Equations Simplified or Rearranged : [1] 9x - 3y = 15 [2] -3x + y = -5Solve by Substitution :// Solve equation [2] for the variable y [2] y = 3x - 5// Plug this in for variable y in equation [1] [1] 9x - 3•(3x-5) = 15 [1] 0 = 0 => Infinitely many solutions

.. hope this helps u ✍️♥️
