Answer 1

Resolva as equações encontrando o valor de x

a)X +3=-24

x+3=-24

x=-24-3

x=-27

b)2x-5=-17

2x=-17+5

2x=-12

x=-12/2

x=-6

c)4x-12=-34+3x

4x-3x=-34+12

x=-22

d)3(x-5)=-16

3x-15=-16

3x=-16+15

3x=-1

x=-1/3

E)-2(x+6)=3(x+16)

-2x-12=3x+48

-2x-3x=48+12

-5x=60

x=60/-5

x=-12

F)x-3x-5=2(x+10)-3

-2x-5=2x+20-3

-2x-5=2x+17

-2x-2x=17+5

-4x=22

x=-22/4

x=-22÷2/4÷2

x=-11/2


G)7x-12=-2•(x-36)

7x-12=-2x+72

7x+2x=72+12

9x=84

x=84/9

x=65/9

espero ter ajudado!

bom dia !

Answer 2

Resolva as equações encontrando o valor de x

a) x + 3 = -24, x = -24 - 3 = -27

b) 2x - 5 = -17,  2x = -17 + 5 = -12, x = -6

c) 4x - 12 = -34 + 3x

4x - 3x = -34  + 12

x = -22

d) 3(x - 5) = -16  , 3x - 15 = -16, 3x = -1, x = -1/3

E) -2(x + 6) = 3(x + 16)

-2x - 12 = 3x + 48

5x = -60

x = -60/5 = -12

F) x - 3x - 5 = 2(x + 10) - 3

-2x - 5 = 2x + 17

4x = -22, x = -11/2

G) 7x - 12 = -2(x - 36)

7x - 12 = -2x + 72

9x = 84, x = 84/9
