Question

ayúdenme por favor
doy puntos altos porfis

Answer 1

Explicación paso a paso:

a) x+10 =29

x=29-10

x=19

b)6x=48

x=48/6

x=8

c) 10x-2=28

10x=28+2

10x=30

x=30/10

x=3

$\frac{4}{5} y - \frac{1}{2} = \frac{2}{4} - \frac{3}{10}y \\ \frac{4y}{5} - \frac{1}{2} = \frac{1}{2} - \frac{3y}{10} \\ 8y - 5 = 5 - 3y \\ 8y + 3y = 5 + 5 \\ 11y = 10 \\ y = \frac{10}{11}$

la incorrecta reria la d) 3y=4 y=4×3 falso

y =4/3

-6x=2....

x= -2/6

x= - 1/3

x-8=36....

x=36+8

x=44

comprobando

x-8=36

44-8=36

16+13x=20-x.....

13x+x=20-16

14x=4

x=4/14

x=2/7
