Question

Which statements are true the ordered pair (1, 2) and the system of equations? y=−2x+4 7x−2y=3 Select each correct answer.

A. The ordered pair (1, 2) is not a solution to the system of linear equations. B.When (1, 2) is substituted into the first equation, the equation is true.
C. When (1, 2) is substituted into the second equation, the equation is true. D. When (1, 2) is substituted into the second equation, the equation is false. E. When (1, 2) ​ is substituted into the first equation, the equation is false. F.The ordered pair (1, 2) is a solution to the system of linear equations.

Answer 1

When (1, 2) is substituted into the first equation, the equation is true.

The ordered pair (1, 2) is not a solution to the system of linear equations.

Answer 2

y = -2x + 4
7x - 2y = 3

in these systems of equations, they give you a point (1, 2) which 1 is x and 2 is y so substitute these numbers instead of x and y to find if they are a solution to it.

y = -2x + 4 (1, 2)
2 = -2(1) + 4
2 = -2 + 4
2 = 2 so this is true.

7x - 2y = 3 (1, 2)
7(1) - 2(2) = 3
7 - 4 = 3
3 = 3 so this is true.

the answer is B and C and F.

hope this helps, God bless!
