Question

Решите уравнение (х+2.4)×3.5=(х-0.3)×7 пожалуйста срочно

Answer 1

3,5х + 8,4 = 7х -2,1
3,5х - 7х = -2,1 - 8,4
- 3,5х = -10,5
х = 3

Answer 2

Solving the Equation

To solve the equation *(x + 2.4) × 3.5 = (x - 0.3) × 7*, we can follow these steps:

1. Expand the equation by multiplying the terms. 2. Simplify the equation by collecting like terms. 3. Solve for the variable *x*.

Let's proceed with solving the equation step by step.

Step 1: Expand the Equation

Expanding the equation *(x + 2.4) × 3.5 = (x - 0.3) × 7* gives us: *(3.5x + 8.4) = (7x - 2.1)*

Step 2: Simplify the Equation

Next, we simplify the equation by collecting like terms: *3.5x - 7x = -2.1 - 8.4* *-3.5x = -10.5*

Step 3: Solve for the Variable *x*

Finally, we solve for the variable *x* by dividing both sides by -3.5: *x = -10.5 / -3.5* x = 3

So, the solution to the equation *(x + 2.4) × 3.5 = (x - 0.3) × 7* is x = 3.
