Equação
x + 7/6 = 11/2 - 5x/3

2 . ( 3x/8 - 2 ) =3 . ( 1 - 7x/4 ) - x

Answer 1

Bom dia!!

a)

$x + \frac{7}{6} = \frac{11}{2} - \frac{5x}{3}$

$x + \frac{5x}{3} = \frac{11}{2} - \frac{7}{6}$

$\frac{3x}{3} + \frac{5x}{3} = \frac{33}{6} - \frac{7}{6}$

$\frac{8x}{3} =\frac{26}{6}$

$\frac{8x}{3} =\frac{13}{3}$

$8x = 13$

$x = \frac{13}{8} = 1,625$

b)

$2.( \frac{3x}{8} -2) = 3.(1 - \frac{7x}{4} ) -x$

$\frac{6x}{8} -4 = 3 - \frac{21x}{4} -x$

$\frac{6x}{8} + \frac{21x}{4} +x = 3 +4$

$\frac{3x}{4} + \frac{21x}{4} + \frac{4x}{4} = 7$

$\frac{28x}{4} = 7 \\ 28x = 7 * 4 \\ 28x = 28 \\ x = 1$

Bons estudos!
