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

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