Question

0,4(x-14)=x-3,1(3x-1)​

Answer 1

0,4 ( х - 14 ) = х - 3,1 ( 3х - 1 )

0,4х - 5,6 = х - 9,3х + 3,1

0,4х - х + 9,3х = 3,1 + 5,6

8,7х = 8,7

х = 8,7 ÷ 8,7

х = 1.

Ответ : х = 1.

Answer 2

To solve the equation 0.4(x - 14) = x - 3.1(3x - 1), follow these steps:

Step 1: Distribute the constants on the right side of the equation. Step 2: Distribute the constants on the left side of the equation. Step 3: Move all the x terms to one side of the equation and the constants to the other side. Step 4: Simplify and solve for x.

Let's go through the steps in detail:

Step 1: 0.4(x - 14) = x - 3.1(3x - 1)

Distribute -3.1 on the right side: 0.4(x - 14) = x - 3.1 * 3x + 3.1

Step 2: Distribute 0.4 on the left side: 0.4 * x - 0.4 * 14 = x - 3.1 * 3x + 3.1

Step 3: Now, let's combine like terms and move the x terms to the left side and constants to the right side: 0.4x - 5.6 = x - 9.3x + 3.1

Step 4: Combine the x terms: 0.4x - 5.6 = -8.3x + 3.1

Now, let's get all the x terms on the left side and constants on the right side: 0.4x + 8.3x = 5.6 + 3.1

Combine the x terms and constants: 8.7x = 8.7

Finally, solve for x: x = 8.7 / 8.7 x = 1

So, the solution to the equation is x = 1.
