If you need to solve this equation you can multiply the both side of equation on (-1). Like that
<span>2 = (-x);
-1·2 = (-1)·(-x)
if you multiply negative and </span><span>positive </span>you'll have negative,
if you multiply negative and <span>negative you'll have </span><span><span>positive. So
</span> 
</span>-2 = x.  or
x = -2.
The answer is -2.

Write the expressions "Four times the difference of a number and 7 is 32", "One third of a number is 12 less than the number its
Anna71 [15]

<u>Part 1)</u> "Four times the difference of a number and 7 is 32"

Let

x--------> the number

we know that

the expressions is equal to

4(x-7)=32

therefore

<u>the answer part 1) is</u>

4(x-7)=32

<u>Part 2)</u> "One third of a number is 12 less than the number itself"

Let

x--------> the number

we know that

the expressions is equal to

\frac{1}{3} x=(x-12 )

therefore

<u>the answer part 2) is</u>

\frac{1}{3} x=(x-12 )

<u>Part 3)</u> "Ten increased by the quotient of a number and 2 is -15"

Let

x---------> the number

we know that

the expressions is equal to

10+ (\frac{x}{2} )= -15

therefore

<u>the answer Part 3) is</u>

10+ (\frac{x}{2} )= -15

<u>Part 4)</u> "One less than the product of a number and 3 is 5 more than the number itself"

Let

x---------> the number

we know that

the expressions is equal to

(3x)-1=5+x

therefore

<u>the answer Part 4) is</u>

(3x)-1=5+x

how do I cancel this out??? this is the only thing I don't understand... have an a on my class but... never get these right...
Rus_ich [418]
You factor the expression first leaving you with \frac{3xy(z-1)}{3xy}
Then you would cancel out 3xy as because there is exactly one on each side. This, in turn, would leave you with z - 1

The bill for five hamburgers and four salads is $9.50. The bill for four hamburgers and five salads is $10.30. What would be the
Sunny_sXe [5.5K]

Answer: the bill for a hamburger is $0.7

the bill for a salad is $1.5

Step-by-step explanation:

Let x represent the bill for a hamburger.

Let y represent the bill for a salad.

The bill for five hamburgers and four salads is $9.50. This means that

5x + 4y = 9.5- - - - - - - - - - - - - - 1

The bill for four hamburgers and five salads is $10.30. This means that

4x + 5y = 10.3 - - - - - - - - - - - - - -2

Multiplying equation 1 by 4 and equation 2 by 5, it becomes

20x + 16y = 38

20x + 25y = 51.5

Subtracting, it becomes

- 9y = - 13.5

y = - 13.5/ - 9

y = 1.5

Substituting y = 1.5 into equation 1, it becomes

5x + 4(1.5) = 9.5

5x + 6 = 9.5

5x = 9.5 - 6 = 3.5

x = 3.5/5 = 0.7
