1. Explain in your own words what it means for an equation to have 'no solution'.
2. Which of the following equations has no solution?
3x + 5 = 3x + 5
2x - 7 = 5x + 2
4(x + 1) = 4x + 5
6x - 1 = 2x + 7
3. An equation has no solution if, after simplifying, you arrive at a statement that is always (e.g., 5 = 7).
4. When solving an equation, if the variable terms on both sides of the equal sign cancel out and the remaining constants are not equal, the equation has .
5. The equation 7x - 3 = 7x + 10 has a solution.
True
False
6. Solve the equation: 5(2x - 3) = 10x + 7. Does it have a solution? Explain.
7. Consider the equation: x + 2 = x + 5. If we imagine both sides of the equation as weights on a balance scale, what would happen if you tried to balance them? Explain why this illustrates an equation with no solution.
