2x-5=14-3x 

x-6=5x+8-x

2y-1=5y+20

 

Answer 1

A)
 
$2x-5=14-3x$

$2x + 3x = 14 + 5$

$5x = 19$

$\boxed{x = \frac{19}{5} }$

B)

$x-6=5x+8-x$

$x-5x+x = 8 + 6$

$-3x = 14$

$3x = -14$

$\boxed{x = \frac{-14}{3} }$

C)

$2y-1=5y+20$

$2y -5y = 20 + 1$

$-3y = 21$

$\boxed{y = \frac{-21}{3} = -7}$

Espero ter ajudado. :))

Answer 2

2x -5 = 14 -3x 
2x + 3x = 14 + 5 
5x = 19
x = 19 / 5


x-6 = 5x+8-x
x - 5x + x = 8 + 6
- 3 x = 14
x = 14 / - 3
x = - 14 / 3



2y-1=5y+20
2y - 5y = 20 + 1 
- 3 y = 21
y = 21 / - 3
y = -7
