Question

(0.7х-2.1)-(0.5-2х)=0.9(3х-1)+0.1

Answer 1

Это уравнение составлено неправильно или там ошибка короче x=1,8

Answer 2

To solve the equation (0.7x - 2.1) - (0.5 - 2x) = 0.9(3x - 1) + 0.1, we can follow these steps:

Step 1: Distribute the 0.9 on the right side of the equation 0.9(3x - 1) + 0.1 = 2.7x - 0.9 + 0.1

Simplifying, we get: 0.9(3x - 1) + 0.1 = 2.7x - 0.8

Step 2: Distribute the negative sign on the left side of the equation (0.7x - 2.1) - (0.5 - 2x) = 0.7x - 2.1 - 0.5 + 2x

Simplifying, we get: (0.7x - 2.1) - (0.5 - 2x) = 2.7x - 2.6

Step 3: Substitute the simplified expressions back into the equation 2.7x - 2.6 = 2.7x - 0.8

Step 4: Simplify the equation To solve the equation, we need to isolate the variable x on one side. However, in this case, we notice that the x terms cancel out on both sides of the equation.

2.7x - 2.6 = 2.7x - 0.8

If we subtract 2.7x from both sides of the equation, we get:

-2.6 = -0.8

This equation does not have a solution. The cancellation of the x terms on both sides indicates that the original equation is inconsistent and there is no value of x that satisfies the equation.

Therefore, the equation (0.7x - 2.1) - (0.5 - 2x) = 0.9(3x - 1) + 0.1 does not have a solution.
