Question

(08.03)Solve the system of equations and choose the correct answer from the list of options.

d + e = 15
−d + e = −5

Label the ordered pair as (d, e).
(0, 0)
(10, −5)
(5, 10)
(10, 5)

Answer 1

hello :
d + e = 15 ....(1)
−d + e = −5  ....(2)
 (1)+(2) : 2e =10
 e=5
in(1) : d+5=15
d=10 
the pair solution is : (10, 5)

Answer 2

The correct answer is option D. (10, 5)

System of equations:

The system of equations:

d + e = 15                             ....(1)

−d + e = −5                           ....(2)

By adding equation 1 and equation 2 we get:

⇒   d + e = 15 +    -d + e = -15

⇒     2e = 10

⇒       e=5

in equation (1) :

⇒  d+5=15

⇒  d=10

The solution is : (10, 5)

A system of equations comprises two or more equations and seeks common solutions to the equations.
