Question

{y=2x−6, 4x−2y=14 Use the substitution method.

1. the solution is (4,14)
2. The solution is (14,4)
3. There is no solution
4. There are an infinite number of solutions

Answer 1

y=2x-6. ---------(1)
4x-2y=14. --------(2)
substituting equation 2 in 1
4x-2(2x-6)=14
4x-4x+12=14
so it has no solution
