Answer 1

x + 1,2x - 3,6x = - 7

- 1,4x = - 7

x = 5

Ответ : 5

Answer 2

To solve the equation $X + 1.2x - 3.6x = -7$, we need to combine like terms and then isolate $x$. Here's the step-by-step solution:

Step 1: Combine like terms on the left side of the equation: $X + 1.2x - 3.6x = -7$

Combine $1.2x$ and $-3.6x$ by subtracting: $X - 2.4x = -7$

Step 2: Isolate $x$ by moving the constant term to the other side: Subtract $X$ from both sides: $-2.4x = -7 - X$

Step 3: Since there are no coefficients or terms other than $x$ on the left side, we can express the right side as a single term: $-2.4x = -X - 7$

Step 4: Now, we want $x$ to be positive, so we'll multiply the whole equation by $-1$ to change the sign: $2.4x = X + 7$

Step 5: To solve for $x$, divide both sides by $2.4$: $x = \frac{X + 7}{2.4}$

So the solution for $x$ in terms of $X$ is: $x = \frac{X + 7}{2.4}$
