Question

B+(7-b)-(14-b)=? -2(x-3)+4(x+1)=? срочноооооооо

Answer 1

Ответ:

Пошаговое объяснение:

b + 7 - b - 14 + b = b - 7

-2x + 6 + 4x + 4 = 2x + 10

Answer 2

b+7-b-14+b

b-7

-2x+6+4x+4

2x+10

Answer 3

Let's solve the given expressions step by step:

1. B+(7-b)-(14-b):

First, combine like terms: B + 7 - b - 14 + b

Next, simplify the expression: (B - b) + (7 - 14)

Further simplification: (B - b) - 7

The final result is: B - b - 7

2. -2(x-3) + 4(x+1):

Distribute the coefficients: -2x + 6 + 4x + 4

Combine like terms: (-2x + 4x) + (6 + 4)

Simplify the expression: 2x + 10

The final result is: 2x + 10
