If you would like to solve the equation 2 * (2 * x - 10) - 8 = - 2 * (14 - 3 * x), you can calculate this using the following steps:

2 * (2 * x - 10) - 8 = - 2 * (14 - 3 * x)
2 * 2 * x - 2 * 10 - 8 = - 2 * 14 + 2 * 3 * x
4 * x - 20 - 8 = - 28 + 6 * x
4 * x - 6 * x = - 28 + 20 + 8
- 2 * x = 0
x = 0

The correct result would be 1 solution: x = 0.

$2(2x-10)-8=-2(14-3x) \\ \\ 4x - 20 - 8 = -28 + 6x \ / \ expand \\ \\ 4x - 28 = -28 + 6x \ / \ simplify \\ \\ 4x - 28 = 6x - 28 \ / \ regroup \ the \ terms \\ \\ 4x = -6x\ / \ cancel \ -28 \ out \\ \\ 4x - 6x = 0 \ / \ move \ terms \ to \ one \ side \\ \\ -2x = 0 \ / \ simplify \\ \\ x = 0 \ / \ divide \ each \ side \ by \ -2 \\ \\$

So, you're answer to this problem is one solution (x = 0).

A fruit stand has to decide what to charge for their produce. They need $10 for 44 apples and 44 oranges. They also need $15 for

Bess [88]

Step-by-step explanation:

Let x be the price of an apple and y be the price of an orange.

We have been given that a fruit stand need $10 for 4 apples and 4 oranges. We can represent this information as:

$4x+4y=10...(1)$

We are also told that they need $15 for 6 apples and 6 oranges. We can represent this information as:

$6x+6y=15...(2)$

Therefore, our desired system of equations will be:

$4x+4y=10...(1)$

$6x+6y=15...(2)$

The denominator of a fraction is two more than the numerator. If both numerator and denominator are decreased by six, the simpli

ira [324]

Answer:

$\dfrac{40}{42}$

Step-by-step explanation:

Let the numerator of the fraction=x

Since the denominator of a fraction is two more than the numerator.

Denominator=x+2

The fraction is therefore:

$\dfrac{x}{x+2}$

If both numerator and denominator are decreased by six, the fraction becomes:

$\dfrac{x-6}{x+2-6}$

The simplified result is $\dfrac{17}{18}$

Therefore:

$\dfrac{x-6}{x+2-6}=\dfrac{17}{18}\\$Next, we solve for x\\Cross multiply\\18(x-6)=17(x+2-6)\\18(x-6)=17(x-4)\\Expand the bracket\\18x-108=17x-68\\Collect like terms\\18x-17x=-68+108\\x=40$
