Question

Y=2x+1
x-y=-3
is (2,5) a solution of the system?

Answer 1

YES

Explanation:

Answer 2

(2,5) is the solution of the system

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)
