Question

1/5(3x-4)+1/6(3x+1)=7/15

Answer 1

$\frac{1}{5} (3x - 4) + \frac{1}{6}(3x + 1) = \frac{7}{15 } \\ \frac{3x - 4}{5} + \frac{3x + 1}{6} = \frac{7}{15} \\ \frac{18x - 24 + 15x + 5}{30} = \frac{7}{15} \\ \frac{3x19}{3} = \frac{7}{15} \\ \frac{3x - 19}{2} = 7 \\ 3x - 19 = 14 \\ 3x = 14 + 19 \\ x = \frac{33}{3} \\ x = 11$
