Answer 1

д)

$\frac{2x-1}{3} -3=\frac{x}{4} \\\\\frac{2x-1}{3} -\frac{9}{3} =\frac{x}{4} \\\\\frac{2x-10}{3} =\frac{x}{4} \\\\3x=4(2x-10)\\\\3x=8x-40\\\\5x=40\\\\x=8$

е)

$\frac{5x-2}{3} -\frac{4x-3}{5} =6\\\\\frac{5(5x-2)}{15} -\frac{3(4x-3)}{15} =6\\\\\frac{25x-10}{15} -\frac{12x-9}{15} =6\\\\\frac{25x-10-12x+9}{15} =6\\\\\frac{13x-1}{15} =6\\\\13x-1=15*6\\\\13x-1=90\\\\13x=91\\\\x=7$
