Answer 1

Răspuns:

$\frac{4}{5} + 2x = \frac{3}{2} \\ \\ 2x = \frac{3}{2} - \frac{4}{5} = \\ \\ = \frac{15}{10} - \frac{8}{10} = \\ \\ = \frac{7}{10} \\ \\ x = \frac{7}{20}$

Answer 2

Explicație pas cu pas:

ღSalutare!ღ

$b) \frac{4}{5} + 2x = 1 \frac{1}{2} \\ \frac{4}{5} + 2x = \frac{1 \times 2 + 1}{2} \\ \frac{4}{5} + 2x = \frac{3}{2} \\ 2x = ^{5)} \frac{3}{2} - ^{2)} \frac{4}{5} \\ 2x = \frac{15}{10} - \frac{8}{10} \\ 2x = \frac{15 - 8}{10} \\ 2x = \frac{7}{10} \\ x = \frac{7}{10} \div 2 \\ x = \frac{7}{10} \times \frac{1}{2} \\ \red{ x = \frac{7}{20} }$

Succes!!;)
