Answer 2

Ответ:

Пошаговое объяснение:

17 - 4x = 42 - x - 7

Х-4х=42-7-17

-3х=18

Х=18:(-3)

Х=-6

2) 5 - 4x + 9 = 2x - 10

-4х-2х=-10-9-5

-6х=-24

Х=-24:(-6)

Х=4

Answer 3

1. To solve the equation 17 - 4x = 42 - x - 7, we can start by simplifying both sides of the equation:

17 - 4x = 42 - x - 7 10 - 4x = -x

Next, we can isolate the variable on one side of the equation by adding 4x to both sides:

10 = 3x

Finally, we can solve for x by dividing both sides by 3:

x = 10/3 or 3.33 (rounded to two decimal places)

Therefore, the solution to the equation is x = 10/3 or 3.33.

2. To solve the equation 5 - 4x + 9 = 2x - 10, we can start by simplifying both sides of the equation:

14 - 4x = 2x - 10

Next, we can isolate the variable on one side of the equation by adding 4x to both sides and adding 10 to both sides:

24 = 6x

Finally, we can solve for x by dividing both sides by 6:

x = 4

Therefore, the solution to the equation is x = 4.
