Question

Por favor alguém me ajuda!!

Answer 1

4x + $\frac{1}{2}$ = $\frac{9}{2}$

x = 1

4*1 + $\frac{1}{2} = \frac{9}{2}$

4 + $\frac{1}{2} = \frac{9}{2}$

$\frac{2*4}{2} + \frac{1}{2} = \frac{9}{2}$

$\frac{8}{2} + \frac{1}{2} = \frac{9}{2}$

$\frac{8+1}{2}= \frac{9}{2}$

$\frac{9}{2}= \frac{9}{2}$

Sim , 1 é raiz da equação $4x + \frac{1}{2}= \frac{9}{2}$

Answer 2

4*1+$\frac{1}{2}$=$\frac{9}{2}$
4+0.5=4.5
4.5=4.5
