Question

3 (17 - 22,1x) = -7 - 63,4x;​

Answer 1

Ответ:

51 - 66,3х = - 7 - 63,4х

-66,3х + 63,4х = - 7 - 51

-2,9х = -58

х = - 58 ÷ (-2,9)

х = 20

Answer 2

To solve the given equation, let's simplify and solve for x:

3(17 - 22.1x) = -7 - 63.4x

Start by distributing the 3 on the left side of the equation:

51 - 66.3x = -7 - 63.4x

Next, combine like terms by adding 66.3x to both sides:

51 = -7 + 3.1x

Now, simplify the right side of the equation:

51 = -7 + 3.1x

Combine the constants on the right side:

51 = 3.1x - 7

Add 7 to both sides:

58 = 3.1x

Finally, divide both sides by 3.1 to solve for x:

x = 58 / 3.1 ≈ 18.71

Therefore, the solution to the equation is x ≈ 18.71.
