if u will answer correctly I will mark u as brainlist ​

Answer 1

$\sf\frac{x - 1}{2} - \frac{x - 4}{5} = 10 \\ \sf \: taking \: lcm \: of \: 2 \: and \: 5 \: we \: get \: 10 \\ \sf \: \frac{5x - 5 - 2x - 8 }{ 10} = 10 \\ \sf \: \frac{3x - 13}{10} = 10 \\ \sf \: by \: cross \: multiplication \: we \: get \\ \sf \: 3x - 13 = 10 \times 10 \\ \sf \: 3x - 13 = 100 \\ \sf \: 3x = 100 + 13 \\ \sf \: 3x = 113 \\ \sf \:x = \frac{113}{3} \\ \sf \: x = 37.6......$
