What number should both sides of the following equation be divided by to solve for x?(6.4)x = 32

4
6.4
6
5

Answers

In algebraic equations, it is easier to solve for an unknown term when that term is being isolated on one side of the equation. In the given equation, the unknown term "x" is not isolated because it is being multiplied by 6.4. To solve for x, it is essential to divide both sides by 6.4 to isolate x. It is shown as follows:

6.4x = 32

Dividing both sides by 6.4:
(6.4x)/6.4 = 32 / 6.4

x = 5

Therefore, 6.4 should be divided to both sides to solve for x.

To solve 493x = 3432x+1, write each side of the equation in terms of base

Answers

Answer

= 3.405 × 10⁻⁴

Explanation

If the question is correctly written, then it is very easy.

First, take the like terms on one side.

493x = 3432x+1

493x - 3432x = 1

-2939x = 1

Dividing both sides by -2939 to get the value of x.

x = 1/(-2939)

= - 0.0003405

= 3.405 × 10⁻⁴
