Question

Tell whether the ordered pair is a solution of the system of linear equations. (Show work)
(3,4)

x+y=3

x-2y=-5

Answer 1

Step-by-step explanation:

x + y = 3 (1)

x - 2y = -5 (2)

On subtracting

x + y - (x - 2y) = 3 - (-5)

x + y - x - 3y = 3 + 5

y - 3y = 8

-2y = 8

y = 8/-2

y = -4

From 1

x + (-4) = 3

x - 4 = 3

x = 4 + 3

x = 7

Therefore, (3,4) is not a solution of the equation
