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)

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

you can not drow on this
