Question

2 – 3(х + 2) = 5 – 2х;

Answer 1

2-3(х+2)=5-2х
2-3х-6=5-2х
-3х+2х=5-2+6
-х=9

Answer 2

To solve the equation 2 - 3(x + 2) = 5 - 2x for the variable x, follow these steps:

1. Distribute the -3 on the left side to both terms inside the parentheses: 2 - 3x - 6 = 5 - 2x

2. Combine like terms on both sides of the equation: (2 - 6) - 3x = 5 - 2x -4 - 3x = 5 - 2x

3. Move all the terms with x on one side of the equation and constants on the other side. You can do this by adding 3x to both sides: -4 - 3x + 3x = 5 - 2x + 3x

This simplifies to: -4 = 5 + x

4. Now, isolate x by moving the constant terms to the other side of the equation. You can do this by subtracting 5 from both sides: -4 - 5 = x

Simplifying: -9 = x

So, the solution to the equation 2 - 3(x + 2) = 5 - 2x is x = -9.
