Answer:
The solution is (4, 0)
Step-by-step explanation:
Using Linear combination method to solve:
[tex]2d + e = 8\\d - e = 4\\[/tex]
Since "e" have the same coefficient in both equation with opposite operator; we will add.
[tex](2d + d) + (e - e) = (8 + 4)\\3d = 12\\[/tex]
Divide both side by coefficient of d which is 3
[tex]\frac{3d}{3} = \frac{12}{3} \\d = 4\\[/tex]
Since d = 4; put 'd' into any of the equation to get 'e'
[tex]2d + e = 8\\2(4) + e = 8\\8 + e = 8\\e = 8 - 8\\e = 0\\[/tex]
Therefore, the solution is (4, 0)
