Answer: Dakota can know for sure by substituting x as 13/8 into the original equation to find if the solution equals 8.
After substitution, 12.5 ≠ 8. So, Eva's solution is incorrect.
Step-by-step explanation:
[tex]4(x + \frac{3}{2} ) = 8\\4(\frac{13}{8} +\frac{3}{2} ) = 8\\\frac{52}{8} + \frac{12}{2} = 8 \\\frac{52}{8} + \frac{48}{8} = 8\\\frac{100}{8} = 12.5 \neq 8[/tex]
