Question

−x−2+3(x−3)=3(−x+4)−3 объясните как тут раскрываются скобки

Answer 1

-х-2+3х-9=-3х+12-3 2х-11=-3х+12-3 2х+3х=12-3+11 5х=20 х=4 Число за скобками (3) умножается на каждое число в скобках. Знаки меняются , если умножаешь на минус.

Answer 2

Solving the Equation and Expanding the Brackets

To solve the equation -x - 2 + 3(x - 3) = 3(-x + 4) - 3, we need to expand the brackets and simplify the expression.

Expanding the brackets, we get: -x - 2 + 3x - 9 = -3x + 12 - 3

Simplifying further: 2x - 11 = -3x + 9

Adding 3x to both sides: 5x - 11 = 9

Adding 11 to both sides: 5x = 20

Dividing by 5: x = 4

So, the solution to the equation is x = 4.

This solution is obtained by simplifying the given equation step by step.
