Question

a) 3(x+2)=10+2x

b)12m+6=5m-15-4

c)5x+3+2x=7x-9+2x

d)-10p+7-p+13p=0

e)24-17=6x-2x+9x​

Answer 1

Resposta:

a)x= 4

b) m= 25/7

c) x= 6

d) p= 24/7

e) x=7/13

Explicação passo-a-passo:

a) 3x + 6 = 10 + 2x

3x-2x= 10-6

x = 4

b) 12m -5m= -15-4-6

7m= -25

m= -25/7 (-1)

m= 25/7

c) 5x+2x-7x-2x=3+9

-2x= 12

x= 12/2

x= 6

d) -10p -p+13p=0-7

24p = 7

P= 24/7

e)7=13×

-13×=7 (-1)

x= 7/13

Answer 2

Oie, Td Bom?!

a)

3(x + 2) = 10 + 2x

3x + 12 = 10 + 2x

3x - 2x = 10 - 12

x = - 2

b)

12m + 6 = 5m - 15 - 4

12m + 6 = 5m - 19

12m - 5m = - 19 - 6

7m = - 25

m = - 25/7

c)

5x + 3 + 2x = 7x - 9 + 2x

5x + 3 = 7x - 9

5x - 7x = - 9 - 3

- 2x = - 12

x = -12/-2

x = 12/2

x = 6

d)

- 10p + 7 - p + 13p = 0

2p + 7 = 0

2p = - 7

p = - 7/2

e)

24 - 17 = 6x - 2x + 9x

7 = 13x

13x = 7

x = 7/13
