What is the result of adding the system of equations?
2x + y = 4, 3x - y = 6
Solution:
Given: A system of linear equations
2x + y = 4
3x - y = 6
By adding both the equations, we eliminate the variable y.
5x = 10
Dividing both sides by 5
x = 2
Substituting the value of 2 in either of the equations
2x + y = 4
2 (2) + y = 4
By further calculation
4 + y = 4
y = 4 - 4 = 0
Therefore, the result of adding the system of equations is (2, 0).
What is the result of adding the system of equations?
Summary:
The result of adding the system of equations 2x + y = 4 and 3x - y = 6 is (2, 0).
