Which ordered pair (c, d) is the solution to the given system of linear equations?
-c+2d=13
|-9c-4d=-15

(-1, 6)

Step-by-step explanation:

{-c + 2d = 13

{-9c - 4d = -15

-⅑[-9c - 4d = -15]

{-c + 2d = 13

{c + 4⁄9d = 1⅔ >> New equation

2 4⁄9d = 14⅔

2 4⁄9 2 4⁄9

d = 6 [Plug this back into both equations to get the c-value of -1]; -1 = c

(-1,6)

Step-by-step explanation:

We are given that system of linear equations

We have to find the value of ordered pair (c,d).

Equation first multiply by 2 then add to equation second

We  get

Substitute the value of c in equation first then, we get

Hence, the ordered pair (-1,6) is the solution of given system of linear equations.

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
