Answer 1

Ответ:

3х-3+4х+4=6х+12

3х+4х-6х=12+3-4

х=11

Объяснение:

Раскрыла скобки, переместила неизвестные в левую сторону, а исвестные в правую, всё решила.

Answer 2

Ответ:

3(x-1)+4(x+1)=6(x+2)

3х-3+4х+4=6х+12

3х+4х-6х=(+)12+3-4

1х=11

х=11

Удачи!!!

Answer 3

Let's solve the equation step by step:

3(x - 1) + 4(x + 1) = 6(x + 2)

First, let's simplify the equation by distributing the coefficients:

3x - 3 + 4x + 4 = 6x + 12

Combine like terms on both sides:

(3x + 4x) + (-3 + 4) = 6x + 12

7x + 1 = 6x + 12

Next, let's isolate the x term on one side by subtracting 6x from both sides:

7x - 6x + 1 = 6x - 6x + 12

x + 1 = 12

Finally, to solve for x, we subtract 1 from both sides:

x + 1 - 1 = 12 - 1

x = 11

Therefore, the solution to the equation 3(x - 1) + 4(x + 1) = 6(x + 2) is x = 11.
