Solve.
{ 2d+e=8
{d-e-4
use the linear combination method.

there are infinitely many solutions.

there is no solution.

the solution is (4, 0).

the solution is (5, - 2).

The solution is (4, 0)

Step-by-step explanation:

Using Linear combination method to solve:

Since "e" have the same coefficient in both equation with opposite operator; we will add.

Divide both side by coefficient of d which is 3

Since d = 4; put 'd' into any of the equation to get 'e'

Therefore, the solution is (4, 0)
