Step 1

Solve the system of equations.

Step 1.1

Add the two equations together to eliminate $x$ from the system.

Step 1.2

Since $0 \neq 6$ , there are no solutions.

No solution

Step 2

Since the system has no solution, the equations and graphs are parallel and do not intersect. Thus, the system is inconsistent.

Inconsistent
