Question

$\frac{3x-4}{6} = \frac{7}{8}$

Answer 1

$8(3x - 4) = 42 \\ \\ 24x - 32 = 42 \\ \\ 24x = 42 + 32 \\ \\ 24x = 74 \\ \\ x = \frac{37}{12} = 3 \frac{1}{12}$

Answer 2

$\frac{3x-4}{6}=\frac{7}{8}\\\\3x-4=\frac{7\cdot 6}{8}\\\\3x-4=\frac{21}{4}\\\\3x=\frac{21}{4}+4\\\\3x=\frac{37}{4}\\\\x=\frac{37}{4\cdot 3} \\\\x=\frac{37}{12}\\\\x=3\frac{1}{12}$
