Question

7х-(х+3)=3(2х-1) помогите срочно надо

Answer 1

7x-(x+3)=3(2x-1)
7x-x-3=6x-3
6x-3=6x-3
6x-6x=3-3
0x=0
x- любое число
Ответ: x∈(-∞;+∞)

Answer 2

Solving the Equation

To solve the equation 7x-(x+3)=3(2x-1), we can follow these steps:

1. Combine like terms on the left side of the equation. 2. Distribute the 3 on the right side of the equation. 3. Combine like terms on the right side of the equation. 4. Solve for x.

Step 1: Combine Like Terms

The equation 7x-(x+3)=3(2x-1) simplifies to 6x - 3 = 6x - 3 after combining like terms on the left side.

Step 2: Distribute the 3

Distributing the 3 on the right side of the equation gives us 6x - 3 = 6x - 3.

Step 3: Combine Like Terms on the Right Side

After distributing the 3, the equation remains 6x - 3 = 6x - 3.

Step 4: Solve for x

Since the equation simplifies to 6x - 3 = 6x - 3, we can see that the left side is equal to the right side. This means that the equation has infinitely many solutions. In other words, any value of x will satisfy the equation.

Therefore, the solution to the equation 7x-(x+3)=3(2x-1) is that x can be any real number.
