Question

12.- 2 (5b + 2) -2b=3(2b + 3) +7​

Answer 1

Respuesta:

12. b = 6

Explicación paso a paso:

2(5b + 2) -2b = 3(2b + 3) +7

10b + 4 -2b = 6b + 9 +7

8b + 4 = 6b + 16

8b - 6b = 16 - 4

2b = 12

b = 6

Answer 2

Respuesta:

-2(5b+2)-2b=3(2b+3)+7

10b+4-2b=3(2b+3)+7

10b+4-2b=6b+9+7

8b+4=6b+9+7

8b+4=6b+16

8b-6b+4=16

8b-6b=16-4

2b=16-4

2b=12

b=12/2

b=6
