Question

-3(1-3b)-12=12 1-4x=2(x+2)+(4x-1)3 1-4=2(x+2)+4x-1)3 10 баллов

Answer 1

-3(1-3b)-12=12

-3(1-3b)-12=12-3 + 9b-12=12

9b= 12+3+12

9b= 27

b= 3

1-4x=2(x+2)+(4x-1)3

1-4x= 2x+4+12x-3

-4x-2x-12x= 4-3-1

-18x= 0

x=0

Answer 2

Ответ:

-3+9в-12=12

9в-15=12

9в=27

в=3

1-4х=2х+4+12х-3

[меняем местами], решаем дальше

14x+1=1-4x

18x=0

x=-18

понятней напиши, а то там скобка нитуда, нисюда

Answer 3

It appears that you have written a series of equations, but they contain some errors and are not entirely clear. Let's try to address them one by one:

1. -3(1-3b) - 12 = 12 To solve this equation for 'b', let's simplify it step by step:

Distribute the -3 on the left side: -3 + 9b - 12 = 12

Combine like terms: 9b - 15 = 12

Add 15 to both sides: 9b = 27

Now, divide both sides by 9: b = 3

So, the solution for 'b' is 3.

2. 1-4x = 2(x+2) + (4x-1)3 It seems there is a missing operator before the "(4x-1)3". I assume you meant to write:

1-4x = 2(x+2) + 3(4x-1)

Let's solve this equation for 'x':

Distribute the 2 and 3 on the right side: 1-4x = 2x + 4 + 12x - 3

Combine like terms: 1-4x = 14x + 1

Move all 'x' terms to one side and the constant terms to the other side: 1 - 1 = 14x + 4x

Simplify further: 0 = 18x

Now, since any number multiplied by zero is zero, x can be any value. Therefore, this equation has infinite solutions.

Note: There is no "10 баллов" equation provided, so I'm not sure what you meant by that.
