Answer 2

Ответ:

Пошаговое объяснение:

раскрываем скобки, если перед скобкой -, то знак в скобке меняем на противополож.

-3х-2х+7-2х+7=-6х+18

-3х-2х-2х+6х=18-7-7

-х=4

х=-4

Answer 3

To solve the equation, let's simplify and solve for the variable 'x':

Step 1: Distribute the coefficients where necessary. -3x + (-2x + 7) - (2x - 7) = 3(-2x + 6)

Step 2: Simplify the expressions inside the parentheses. -3x - 2x + 7 - 2x + 7 = -6x + 18

Step 3: Combine like terms on the left side. (-3x - 2x - 2x) + (7 + 7) = -6x + 18

Step 4: Simplify the left side further. -7x + 14 = -6x + 18

Step 5: Move all terms with 'x' to the left side and the constant terms to the right side of the equation. -7x + 6x = 18 - 14

Step 6: Combine like terms on both sides of the equation. -1x = 4

Step 7: Solve for 'x' by dividing both sides by the coefficient of 'x', which is -1. x = 4 / -1 x = -4

The solution to the equation is x = -4.
