1. Stating the problem: Solve the system of linear equations:
$$-5 + 3x = 16$$
$$4x - 11 = -3$$
2. Solve the first equation for $x$:
Add 5 to both sides:
$$-5 + 3x + 5 = 16 + 5$$
$$3x = 21$$
Divide both sides by 3:
$$\cancel{3}x = \frac{21}{\cancel{3}}$$
$$x = 7$$
3. Verify the solution in the second equation:
Substitute $x = 7$:
$$4(7) - 11 = -3$$
$$28 - 11 = -3$$
$$17 \neq -3$$
Since $x=7$ does not satisfy the second equation, solve the second equation separately:
Add 11 to both sides:
$$4x - 11 + 11 = -3 + 11$$
$$4x = 8$$
Divide both sides by 4:
$$\cancel{4}x = \frac{8}{\cancel{4}}$$
$$x = 2$$
4. Conclusion: The two equations give different values for $x$ ($7$ and $2$), so the system has no solution (the lines are parallel).
Final answer: No solution (inconsistent system).
