Use substitution to determine the solution of the system of equations.

y = - 2x - 7

2y - x = 1

A. (-1,0)

B. (212,-28)

C. (-6,-52)

D. (-3,-1)

Option D is correct

(-3, - 1)

Step-by-step explanation:

equation 1 is

y = - 2x - 7

and equation 2 is

2y - x = 1

so from 1 we have y = - 2x - 7 put in 2

2 (-2x - 7) - x = 1

-4x - 14 - x = 1

- 5x = 1 + 14

X = 15/-5

X = - 3

put in equation 1

Y = - 2 (-3) - 7

Y = 6 - 7

Y = - 1
