Question

RESOLVA AS EQUAÇÕES:
a) 12 x -10 = 5x +11
b) 7y + 5 = 68 – 2y
c) 14 – 3w = 2w + 29
d) 8t – 9 = 2t + 11

Answer 1

Resposta:

Explicação passo-a-passo:

a) 12x-5x=21

7x=21

x=3

b) 7y+2y=63

9y=63

y=7

c) -3w-2w=29-14

-5w=15

w=-3

d) 8t-2t=20

6t=20

t=10/3

Answer 2

Resposta:

a) 12x -10 = 5x + 11

7x = 21

x = 3

b) 7y + 5 = 68 – 2y

9y = 63

y = 7

c) 14 – 3w = 2w + 29

5w = 15

w = 3

d) 8t – 9 = 2t + 11

6t = 20

t = 20/6 = 10/3
