Question

решите уравнение по математике

Answer 1

$\frac{2x + 1}{3} = \frac{1}{2} \\ 2(2x + 1) = 3 \\ 4x + 2 = 3 \\ 4x = 1 \\ x = \frac{1}{4}$

Answer 2

$\frac{2x + 1}{3} = \frac{1}{2} \\ \frac{6(2x + 1)}{3} = \frac{6}{2} \\ 2(2x + 1) = 3 \\ 4x + 2 = 3 \\ 4x = 3 - 2 \\ 4x = 1 \\ x = 1 \div 4 \\ x = 0.25$
