Question

What is the solution to the system of equations?

2x – y = 7

y = 2x + 3

(2, 3)
(2, 7)
no solution
infinite number of solutions

Answer 1

-you can draw the two lines and see if they intersected or not, any intersection point is a solution for the system
if there is no intersection points (the two lines are parallel) then there is no solution for this system

Answer 2

no solution.
2 x - (3 + 2 x) = 7
-3 != 7
