Which ordered pair is the best estimate for the solution to the system?​

See explanation

Step-by-step explanation:

13x + 6y = - 30 (1)

x - 2y = -4 (2)

Multiply (2) by 3

3x - 6y = -12 (3)

13x + 6y = - 30 (1)

Add (3) and (1) to eliminate y

3x + 13x = -12 - (-30)

16x = -12 + 30

16x = 18

x = 18/16

x = 1.125

Substitute x = 1.125 into (2)

x - 2y = -4 (2)

1.125 - 2y = -4

-2y = -4 - 1.125

-2y = -5.125

y = -5.125/-2

y = 2.5625

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
