Y=2x+1

x-y=-3

is (2,5) a solution of the system?

(2,5) is the solution of the system

Step-by-step explanation:

x = 2, y = 5

if we substitute this values in equation y = 2x + 1

y = 2 (2) + 1 = 5 (true for y and x in equation (1))

Let's check for x - y = - 3

x = - 3 + y = - 3 + 5 = 2 ((true for y and x in equation (2) also)
