Answer:
4x + 5y = 15
-4x + y = 7
6y = 22
y = 22/6 = 11/3
-4x + 11/3 = 21/3
-4x = 10/3
x = -40/3
Step-by-step explanation:
Using the multiplication property, we have the following equivalent system of linear equations:
- 4/9x + 4/3y = 20/12
- 2/3x - 4/3y = 5/3
<h3>What is an Equivalent System of Linear Equations?</h3>
- Systems that are equivalent will have the same solution.
- Creating equivalent system helps us to find the variables in a system of equations.
Given:
1/3x + y = 5/4 ---> Equation 1
2/3x - 4/3y = 5/3 ---> Equation 2
To create an equivalent system, multiply equation 1 by 4/3, and multiply equation 2 by 1.
Thus, using the multiplication property, we have the following equivalent system of linear equations:
- 4/9x + 4/3y = 20/12
- 2/3x - 4/3y = 5/3
