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

Solution:

2x - y = 7 …. (1)

y = 2x + 3 …. (2)

Let us use the substitution method to solve the system of linear equations

Substituting equation (2) in (1)

2x - (2x + 3) = 7

By further calculation

2x - 2x - 3 = 7

-3 = 7

Therefore, there is no solution.

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

Summary:

The system of equations 2x - y = 7 and y = 2x + 3 has no solution.
