Question

resolva as equações:

a: 4X+3=-19

b: 5X+2=2X-1

c: 6-3X=-10-4X

d: 2(3X-5)=14

e: 2X-1=3÷5=3

valendo 25 pontos ​

Answer 1

$4x = - 19 - 3 \\ 4x = - 22 \\ x = \frac{ - 22}{ \: \: \: 4} \\ x = \frac{ - 11}{ \: \: \: 2}$

b)

$5x - 2x = - 1 - 2 \\ 3x = - 3 \\ x = \frac{ - 3}{ \: \: \: 3} \\ x = - 1$

c)

$- 3x + 4x = - 10 - 6 \\ x = - 16$

d)

$6x - 10 = 14 \\ 6x = 14 + 10 \\ 6x = 24 \\ x = \frac{24}{6} \\ x = 4$
