Write the sentence as an equation, using x as the variable. Then find the solution of the equation from the set of integers bet

Inessa05 [86]

Answer:

The solution of given equation is x = -4

Step-by-step explanation:

We are given the following in the question:

Let x be the variable such that

$x \in (-12,12)$

Relation:

The quotient of a number and 4 is negative 1

We can write the equation as:

$\dfrac{x}{4} = -1$

Solution:

$\dfrac{x}{4} = -1\\\\\Rightarrow x = 4\times -1\\\Rightarrow x = -4$

Thus, the solution of given equation is x = -4

What is the solution: 256x + 2 = 43x + 9

ruslelena [56]

Answer:

$x = \bf \frac{7}{213}$

Step-by-step explanation:

To find the solution to the equation, we have to rearrange the equation to make $x$ the subject:

$256x + 2 = 43x + 9$

⇒ $256x + 2 - 2 = 43x + 9 - 2$ [Subtracting 2 from both sides]

⇒ $256x = 43x + 7$

⇒ $256x - 43x = 43x + 7 - 43x$ [Subtracting $43x$ from each side]

⇒ $213x = 7$

⇒ $\frac{213}{213}x = \frac{7}{213}$ [Diving both sides by 213]

⇒ $x = \bf \frac{7}{213}$
