Equation Substitution 03Fc9F

1. **State the problem:** We are given two equations: $$2x + 8y = 3$$ and $$x + 4y = 8$$ and values $$x = -24$$ and $$y = 26$$. We need to check if these values satisfy the equations. 2. **Substitute values into the first equation:** $$2(-24) + 8(26) = -48 + 208 = 160$$ 3. **Check if the left side equals the right side:** The right side is $$3$$, but the left side is $$160$$, so the values do not satisfy the first equation. 4. **Substitute values into the second equation:** $$-24 + 4(26) = -24 + 104 = 80$$ 5. **Check if the left side equals the right side:** The right side is $$8$$, but the left side is $$80$$, so the values do not satisfy the second equation either. 6. **Conclusion:** The values $$x = -24$$ and $$y = 26$$ do not satisfy either equation.
