Question

a) x+3/5=-1 ? ; b) y-2=3/2 ; c) 2z+3=z+2/3 ; d) x+5/2 = 8+2x/5 ;. obs: por favor com cálculo

Answer 1

a)$\frac{x+3}{5} = -1$
$\frac{x+3}{5} = \frac{-5}{5}$
$x+3=-5$
$x=-8$

b)$y-2 = \frac{3}{2}$
$\frac{2y-4}{2} = \frac{3}{2}$
$2y-4 = 3$
$2y=7$
$y= \frac{7}{2}$

c)$2z +3 = z+ \frac{2}{3}$
$6z+9=3z+2$
$3z = -7$
$z= \frac{-7}{3}$


d)$\frac{x}{1} + \frac{5}{2} = \frac{8+2x}{5}$
$\frac{10x}{10} + \frac{25}{10}= \frac{2(8+2x)}{10}$
$10x + 25 = 16+4x$
$6x= -9$
$x = \frac{-9}{6}$
$x= \frac{-3}{2}$
