Question

3 (17 – 22,1 x) = -7 -63,4x;​

Answer 1

Ответ:

х = 20

Объяснение:

3 (17 – 22,1 x) = - 7 - 63,4x

51 - 66,3х = -7 - 63,4х

51 + 7 = 66,3х - 63,4х

58 = 2,9х

580 = 29х

х = 580 : 29

х = 20    

Ответ: х = 20                                              

Answer 2

It looks like you have an equation that needs to be solved for the variable "x." Let's go through the steps to solve it:

Given equation: 3(17 - 22.1x) = -7 - 63.4x

Step 1: Distribute the 3 on the left side of the equation: 51 - 66.3x = -7 - 63.4x

Step 2: Move the x terms to one side of the equation and the constants to the other side: -66.3x + 63.4x = -7 - 51

Simplify the left side: -2.9x = -58

Step 3: Divide both sides by -2.9 to solve for x: x = -58 / -2.9 x = 20

So, the solution for the equation is x = 20.
