Question

$\frac{3}{4} u + \frac{1}{2} = - \frac{3}{4} u + 2$
​

Answer 1

Respuesta:

$\frac{3}{4}u+ \frac{3}{4}u= -\frac{1}{2} + 2\\\\\frac{6}{4}u = \frac{3}{2}\\\\\frac{3}{2}u = \frac{3}{2}\\\\u = \frac{\frac{3}{2} }{\frac{3}{2} }\\\\u = \frac{6}{6}\\\\u= 1$

comprobación

$\frac{3}{4}u + \frac{1}{2} = - \frac{3}{4}u + 2$

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

$\frac{3}{4} + \frac{1}{2} = - \frac{3}{4} + 2\\\\\frac{5}{4} =\frac{5}{4}$
