Question

The point (5,-2) is a solution to this system 5x-y=27 -3x+4y=-23. true or false?

Answer 1

Answer:

True

Step-by-step explanation:

To determine if (5, - 2 ) is a solution to the system , substitute the values of x and y into the left side of both equations and if equal to the right side then it is a solution.

5(5) - (- 2)  = 25 + 2 = 27 = right side

- 3(5) + 4(- 2) = - 15 - 8 = - 23 = right side

the point (5, - 2 ) makes both equations true then is a solution to the system.
