Question

Решить уравнение 2х-(3х-4(х-2)+1)

Answer 1

2х-(3х-4(х-2)+1) при х=-0,2, то 2х-(3х-4(х-2)+1)=2х-(3х-4х+8+1)=2х-3х+4х-8-1=3х-9, если х=-0,2, то 3х-9=3*(-0,2)-9=-9,6

Answer 2

To solve the equation, we need to simplify and find the value of x. Let's start step by step:

1. Distribute the -1 inside the parentheses: 2x - (3x - 4(x - 2) + 1) = 2x - 3x + 4x - 8 - 1

2. Combine like terms: 2x - 3x + 4x = 3x (since 2x - 3x + 4x simplifies to 3x) -8 - 1 = -9 (since -8 - 1 = -9)

So the equation becomes: 3x - 9 = 0

3. Now, isolate x by moving the constant term to the other side of the equation: 3x = 9

4. Finally, divide both sides by 3 to solve for x: x = 9 / 3 x = 3

The solution to the equation is x = 3.
