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
[tex] \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} [/tex]
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
