Question

Tell whether the ordered pair (-1, 3) is a solution of the system of linear equations.y= -7x -4y = 8x + 5

Answer 1

To determine if the ordered pair (-1, 3) is the solution of the system, we replace the values of the x-component and y-component in x & y respectively in each function, that is:

`(3)=-7(-1)-4\Rightarrow3=3`
`3=8(-1)+5\Rightarrow3\\e-3`

From these solutions, we can see that the ordered pair (-1, 3) is no solution for the system of linear equations given.
