Question

-3 - 4x = y, если y = 34

Answer 1

-3 - 4x = y, если y = 34

Подставляем...

-3-4х=34

-4х=34+3

-4х=37

х=37:(-4)

х=-9,25

Ответ: х=-9,25

Answer 2

Ответ:

-9.25

Пошаговое объяснение:

1) Подставить вместо у 34:

$- 3 - 4x = 34$

2) Перенести константу в правую часть равенства:

$- 4x = 34 + 3$

3) Сложить числа:

$- 4x = 37$

4) Разделить обе части уравнения на -4:

$x = - \frac{37}{4} = - 9.25$

Answer 3

To find the value of x when y is given as 34, you can substitute the value of y into the equation and then solve for x.

Given equation: -3 - 4x = y

Substitute y = 34 into the equation:

-3 - 4x = 34

Now, to solve for x, you need to isolate x on one side of the equation. Follow these steps:

Step 1: Move the constant term (-3) to the right side by adding 3 to both sides of the equation: -3 + 3 - 4x = 34 + 3

This simplifies to: -4x = 37

Step 2: Now, to isolate x, divide both sides of the equation by -4: (-4x) / -4 = 37 / -4

This simplifies to: x = -37/4

So, the value of x is -37/4 (or -9.25).
