Question

2x-$\frac{1}{2}$=$\frac{3}{4}$

​

Answer 1

Explicație pas cu pas:

$2x - \frac{1}{2} = \frac{3}{4} \\ \\ 2x = \frac{3}{4} + {}^{2)} \frac{1}{2} \\ \\ 2x = \frac{3}{4} + \frac{2 \times 1}{2 \times 2} \\ \\ 2x = \frac{3}{4} - \frac{2}{4} \\ \\ 2x = \frac{3 - 2}{4} \\ \\ 2x = \frac{1}{4} \\ \\ x = \frac{1}{4} \div \frac{2}{1} \\ \\ x = \frac{1}{4} \times \frac{1}{2} \\ \\ x = \frac{1 \times 1}{4 \times 2} \\ \\ \\ \red{\boxed{ x = \frac{1}{8} }}$
