Question

What is the solution to the system of equations 2x-y=7 and y=2x+3

A. (2,3)
B (2,7)
C No solution
D Infinite number of solutions

Answer 1

He is right

Explanation:

:)

Answer 2

Make y the subject in both equations


`2x-y=7`


`-y=-2x+7`


`y=2x-7`

For the second equation


`y=2x+3`

The two equations are parallel because they have the same gradient or slope but different y intercepts.

This type of equations have no solution because they will never intersect.


`<B> NO SOLUTION </B>`

The correct answer is C
