Question

Под корнем: 15-2х=3 заранее спасибо

Answer 1

Если я правильно поняла, всё выражение в левой части находится под корнем? Если так, то возведём обе части в квадрат, чтобы избавиться от корня. Получаем: 15-2х = 9; -2х = 9-15; 2х = 6; х = 3.

Answer 2

Solving the Equation

To solve the equation 15 - 2x = 3 for x, we can follow these steps:

1. Isolate the Variable - First, let's isolate the variable x by moving the constant term to the other side of the equation. We can do this by subtracting 15 from both sides of the equation.

The resulting equation will be: 15 - 15 - 2x = 3 - 15

This simplifies to: -2x = -12

2. Solve for x - To solve for x, we need to get x by itself. Since -2x means -2 times x, we can solve for x by dividing both sides of the equation by -2.

The final step gives us: x = -12 / -2

Therefore, x = 6.

So, the solution to the equation 15 - 2x = 3 is x = 6.
