Question

A) 7,5x - 10 = 3,5x + 6;​

Answer 1

7,5х-10 =3,5х + 6

7,5х - 3,5х =  6+10

4х=16

х=16/4

х=4

Answer 2

To solve the equation $7.5x - 10 = 3.5x + 6$, you want to isolate the variable $x$ on one side of the equation. Here's how you can do that:

Step 1: Get all the $x$ terms on one side and the constants on the other side. You can do this by subtracting $3.5x$ from both sides of the equation:

$7.5x - 3.5x - 10 = 6$

This simplifies to:

$4x - 10 = 6$

Step 2: Add 10 to both sides of the equation to isolate the $4x$ term on the left side:

$4x - 10 + 10 = 6 + 10$

Simplifying further:

$4x = 16$

Step 3: Finally, divide both sides of the equation by 4 to solve for $x$:

$\frac{4x}{4} = \frac{16}{4}$

This gives:

$x = 4$

So, the solution to the equation $7.5x - 10 = 3.5x + 6$ is $x = 4$.
