Answer 1

Respuesta:

Explicación paso a paso:

2u - 6 = 6

2u - 6+ 6 = 6 + 6

2u = 12

2u /2 = 12/2

u = 6

2b + (-8) = -2

2b – 8 = -2

2b - 8 + 8 = -2 + 8

2b = 6

2b /2 = 6/2

b = 3

2b - 6 = -2

2b - 6 + 6 = -2 + 6

2b = 4

2b /2 = 4/2

b = 2

2b + 9 = 1

2b + 9 - 9 = 1 - 9

2b = -8

2b /2 = -8/2

b = -4

2a - 10 = 10

2a - 10 + 10 = 10 + 10

2a = 20

2a /2 = 20/2

a = 10
