ME AJUDEM PRA HOJE !!! ​

Answer 1

Explicação passo-a-passo:

5p=10

p=10/5

p=2

5k-3=17

5k=17+3

5k=20

k=20/5

k=4

2y+3=9

2y=9-3

2y=6

y=6/2

y=3

6n+4=22

6n=22-4

6n=18

n=18/6

n=3

3x-6=-6x+21

3x+6x=21+6

9x=27

x=27/9

x=3

7m+8=15

7m=15-8

7m=7

m=7/7

m=1

6x+13=-5x+8

6x+5x=8-13

11x=-5

x=-5/11

2,9b-5,1=-0,1b+0,9

2,9b+0,1b=0,9+5,1

3b=6

b=6/3

b=2

Resposta:

todas as respostas abaixo.

Explicação passo-a-passo:

a) $5p=10\\p=\frac{10}{5} \\p=2$

b)$5k-3=17\\5k=17+3\\5k=20\\k=\frac{20}{5} \\k=4$

c)$2y+3=9\\2y=9-3\\2y=6\\y=\frac{6}{2}\\y=3$

d)$6n+4=22\\6n=22-4\\6n=18\\n=\frac{18}{6} \\n=3$

e)$3x-6=-6x+21\\3x+6x=21+6\\9x=27\\x=\frac{27}{9} \\x=3$

f)$7m+8=15\\7m=15-8\\7m=7\\m=\frac{7}{7} =0$

g)$6x+13=-5x+8\\6x+5x=8-13\\11x=-5\\x=\frac{11}{-5} =-\frac{11}{5}$

h)$2,9b-5,1=-0,1b+0,9\\2,9b+0,1b=0,9+5,1\\3b=6\\b=\frac{6}{3} =2$
