Question

3x - 4y = -5y = 4x - 2Is (1,2) a solution of the system?​

Answer 1

Replace x with the given x value in the solution to see if it equals the Y value given in the solution:

3x - 4y = -5

3(1) - 4(2) =

3 - 8 = -5

True.

y = 4x-2

y = 4(1) - 2

y = 4-2

y = 2

True.

Yes (1,2) is a solution.
