Answer:

Simplifying the equation:

\frac{2}{3} x - \frac{5}{6} = -\frac{5}{12} x + \frac{1}{4}

Grouping like terms:

\frac{2}{3} x + \frac{5}{12} x= \frac{1}{4} + \frac{5}{6}

⇒ \frac{39}{36} x=\frac{26}{24}

Solving for 'x', we have:

⇒ x=\frac{26}{24}\frac{36}{39}=1

For this case we place the terms with "x" on the left side of the equation, and the terms without "x" on the right side:

\frac {2} {3} x + \frac {5} {12} x = \frac {1} {4} + \frac {5} {6}

We add similar terms:

\frac {24 + 15} {36} x = \frac {6 + 20} {24}\\\frac {39} {36} x = \frac {26} {24}

We simplify both sides:

\frac {13} {12} x = \frac {13} {12}

Dividing by \frac {13} {12} on both sides of the equation:x = 1

Answer:

x = 1

Marizza181 [45]

Answer:

3

Step-by-step explanation:

15 - 2(7 - x) = 7

collect like terms

-2(7 - x) = 7 - 15

-2(7 - x) = -8

divide both sides by -2

7 - x = -8/-2

7 - x = 4

collect like terns

-x = 4 - 7

-x = -3

dividing both sides by -

x = 3

Step-by-step explanation:

Given : The sum of six fifths and six times a number is equal to four fifths subtracted from seven times the number.

To find : The number ?

Solution :

Let the number be 'x'.

The sum of six fifths and six times a number i.e.  \frac{6}{5}+6x

Four fifths subtracted from seven times the number i.e. 7x-\frac{4}{5}

According to question,

\frac{6}{5}+6x=7x-\frac{4}{5}

7x-6x=\frac{6}{5}+\frac{4}{5}

x=\frac{10}{5}

x=2

The required number is 2.

SVEN [57.7K]

Answer:

John needs 3\frac{3}{4}  yards of blue ribbon.

Step-by-step explanation:

We have been given that Jon uses a piece of red ribbon witch is 3/4th yard long. Jon also needs blue ribbon that is 5 times as long as the ribbon. We are asked to find the amount of blue ribbon that John needs.

To find the amount of blue ribbon that John needs, we will multiply amount of red ribbon by 5 as shown below:

\text{Amount of blue ribbon}=5\times \frac{3}{4}

\text{Amount of blue ribbon}=\frac{5\times 3}{4}

\text{Amount of blue ribbon}=\frac{15}{4}

\text{Amount of blue ribbon}=3\frac{3}{4}

Therefore, John needs 3\frac{3}{4}  yards of blue ribbon.
