Пошаговое объяснение:

2.5x-30=3x-30-x

2.5x-3x+x=-30+30

0.5x=0

X=0

Answer 2

To solve the equation 2.5(x - 12) = 3(x - 10) - x, follow these steps:

Step 1: Distribute the terms on both sides of the equation. Step 2: Combine like terms. Step 3: Solve for x.

Let's go through each step:

Step 1: Distribute the terms On the left side of the equation, distribute 2.5 to (x - 12): 2.5(x - 12) = 2.5x - 2.5 * 12 = 2.5x - 30

On the right side of the equation, distribute 3 to (x - 10): 3(x - 10) = 3x - 3 * 10 = 3x - 30

Step 2: Combine like terms The equation now becomes: 2.5x - 30 = 3x - 30 - x

Step 3: Solve for x To isolate x, we will combine the x terms on the right side and move the constant term to the other side of the equation.

Starting with the equation: 2.5x - 30 = 3x - 30 - x

Combine x terms on the right side: 2.5x - 30 = 2x - 30

Now, let's get rid of the constant term (-30) on both sides: Subtract 2x from both sides: 2.5x - 2x - 30 = 2x - 2x - 30 0.5x - 30 = -30

Next, add 30 to both sides to isolate x: 0.5x = 0

Finally, divide both sides by 0.5 to solve for x: x = 0

So, the solution to the equation is x = 0.
