Question

Which table is a justification for the given solution to the system of equations?

(2, −1)
(2, −1)


y={4x−92x−5

Answer 1

Given that y = 4x – 9 and y = 2x - 5 (2 , -1)
substituting equation 1 to the equation 2
Y = 4x – 9
4x – 9 = 2x - 5
2x = 4
x = 2
Substitute 2
Y = 2(2) - 5
Y = -1
So the ordered pair a the solution the system of equtions given
