Question

решите уравнения номер 752 срочно

Answer 1

$1) frac{x}{72} - frac{13}{72} = frac{29}{72} \ x - 13 = 29 \ x = 29 + 13 \ x = 42$
$2) frac{29}{42} - a = frac{11}{42} + frac{13}{42} = frac{24}{42} \ a = frac{29}{42} - frac{24}{42} = frac{5}{42}$
$3)b - frac{3}{17} = frac{15}{17} - frac{6}{17} = frac{9}{17} \ b = frac{9}{17} + frac{3}{17} = frac{12}{17}$
$4)m + frac{13}{43} = frac{29}{43} - frac{5}{43} = frac{24}{43} \ m = frac{24}{43} - frac{13}{43} = frac{11}{43}$
