Question

ache o x nas equações

a) 2X= -16
b)5x-1=-24
c)3x -12 = x+26
d)6(x+2)=5(x-3)
e)12x+15-10x15​

Answer 1

Resposta:

a) x= -16/2 = -8

b)5x= -23 = x=-23/5

c)2x=38 = x=38/2=19

d)6x+12=5x-15 = x=-27

e) ( tá faltando a igualdade)

Answer 2

Olá

2x = -16

2x ÷ 2 = -16 ÷ 2

x = - 16 ÷ 2

x = -8

5x - 1 = -24

5x = - 24 + 1

5x = -23

$x = - \frac{23}{5}$

3x -12 = x+26

3x - x = 26 + 12

2x = 38

x = 19

6(x+2) = 5(x-3)

6x + 12 = 5x - 15

6x - 5x = -15 - 12

x = -27

12x + 15 = 10 × 15

12x + 15 = 150

12x = 150 - 15

12x = 135

$x = \frac{45}{4}$
