Answer 1

Resposta:

a) 6×=2×+28

6x - 2x = 28

4x = 28

x = 28/4

x =7

b) 12×-4=10×+8

12x - 10x = 8 + 4

2x = 12

x = 12/2

x= 6

c) 7×-1=13

7x = 13 + 1

7X = 14

x= 14/2

x= 7

d) 5×-2=-3×+7+6

5x + 3x = 13 + 2

8x = 15

x = 15/8

Answer 2

a) 6×=2×+28

6× - 2× = 28

4× = 28

× = 28/4

× = 7

v = {7}

b) 12×-4=10×+8

12× - 10× = 8 + 4

2× = 12

× = 12/2

× = 6

v = {6}

c) 7×-1=13

7× = 13 + 1

× = 14/7

× = 2

v = {2}

d) 5×-2=-3×+7+6

5× + 3× = 7 + 6 + 2

8× = 15

× = 15/8

v = {15/8}
