Question 4(Multiple Choice Worth 4 points)

Answer 1

Answer:

The solution is $(3, -2)$

Step-by-step explanation:

We have the following system of equations

Equation 1) $d + e = 1$

Equation 2) $-d + e = -5$

To solve the system of equations add equation 1 with equation 2 and solve for variable e.

$d + e = 1$

       +

$-d + e = -5$

--------------------------

$0d + 2e = -4$

$e = -2$

Now substitute the value of e in equation 1 or equation 2 and solve for d.

$d + (-2) = 1\\\\d = 3$

Therefore the solution of the system is the ordered pair

$(3, -2)$
