$5x - 8 = 2x10$
g)
$5x - 10 = 4 - 3x$
preciso por agr​

Answer 1

$5x - 8 = 2x10 \\ 5x - 8 = 20x \\ 5x - 20x = 8 \\ - 15x = 8 \\ x = - \frac{8}{15}$

..

$5x - 10 = 4 - 3x \\ 5x + 3x = 4 + 10 \\ 8x = 14 \\ x = \frac{7}{14}$

Answer 2

Explicação passo-a-passo:

5x-8=2*10

5x-8=20

5x=20+8

5x=28

x=>28/5

5x-10=4-3x

5x+3x=4+10

8x=14

x=14/8(÷2)

x=>7/4
