Question

Determine whether the point (8, 6) is a solution of the system
11x – 8y = 40

-6x + 1y = -42

by substituting the point into each equation. Determine whether the point (8, 6) is a solution of the system
11x – 8y = 40

-6x + 1y = -42

by substituting the point into each equation. @Mathematics

Answer 1

88-48 = 40 this is correct
-48+6 = 42 correct
yes it is

Answer 2

11x – 8y = 40

11(8) – 8(6) = 40

88-48 = 40

40 = 40 ... works

-------------------

-6x + 1y = -42


-6(8) + 1(6) = -42


-48 + 6 = -42


-42 = -42 ... works


Since both equations are satisfied, the ordered pair is indeed a solution.
