Question

Уравненте (х + 4.3)-6 целых 1/2＝2 целых 7/20 срочно

Answer 1

$(x + 4.3) - 6 \frac{1}{2} = 2 \frac{7}{20 } \\ x + \frac{43}{10} - \frac{13}{2} = \frac{47}{20} \\ x - \frac{11}{5} = \frac{47}{20} \\ x = \frac{47}{20} + \frac{11}{5} = \frac{47 + 44}{20} = \frac{91}{20} или, x = 4 \frac{11}{20}$
