Question

Решите уравнения 1) х+7/12=3/4 3) х-3/5=3/8 5) у+2/7=1/3 7) у-3/8=5/32

Answer 1

1) $x + frac{7}{12} = frac{3}{4} \x = frac{3}{4} - frac{7}{12}\x = frac{9}{12} - frac{7}{12}\x = frac{2}{12}\x = frac{1}{6}$

3) $x - frac{3}{5} = frac{3}{8}\x = frac{3}{5} + frac{3}{8}\x = frac{24}{40} + frac{15}{40}\x = frac{39}{40}$

5) $y + frac{2}{7} = frac{1}{3} \y = frac{1}{3} - frac{2}{7}\y = frac{7}{21} - frac{6}{21}\y = frac{1}{21}$

7) $y - frac{3}{8}  = frac{5}{32} \y = frac{5}{32} + frac{3}{8}\y = frac{5}{32} + frac{12}{32}\y = frac{17}{32}$
