Hey there!
The easiest way I could think to do this is by converting your mixed number to an improper fraction and multiplying the fraction by 2, or 2 over 1.
To multiply fractions, you can just multiply the numerators and denominators and simplify, if applicable.
Since you can't simplify this fraction in its improper form, just convert it back into a mixed number.
So, your answer will be
.
Hope this helped you out! :-)
First, multiply 1/2 and 2 by 6 to simplify the equation. Then, subtract 12 from both sides of the equation to get x alone. Finally divide both sides of the equation by 3 to get x on it's own. That is your solution. X=-2/3 I attached a picture of my work. Hope this helped!
Answer:
1. Absolute value
: d. | - 7| = 7
2. All real numbers
: b. 3x = 3x
3. x = -5 : c. 5x = -25
4. No solution
: a. |2x| = -10
5. Adding the opposite to both sides of the equation.
: e. Canceling
Step-by-step explanation:
1. Absolute value
: d. | - 7| = 7
The absolute value is considered the distance to 0... so if there's a negative sign in the value, the negative sign disappears.
2. All real numbers
: b. 3x = 3x
If we divide both sides by 3, we have x = x, which will always be true.
3. x = -5 : c. 5x = -25
If we multiply each side by 5, we have 5(x) = 5(-5) thus 5x = -25
4. No solution
: a. |2x| = -10
The result of an absolute value cannot be a negative number. So, that has no solution since there's no value of x that would make this true.
5. Adding the opposite to both sides of the equation.
: e. Canceling
If you have for example (x = -5) and you add 5 on both sides, you cancel the value on the right side... (becomes x + 5 = 0).
Remove the brackets on the left
10 - 9x + 120 = - 9x You get a bizarre result no matter what you try to do to resolve this. If you say any number will do pick, a number at random for x. Say 10
10 - 90 + 120 = -90 Is this statement true? No. You only need 1 exception but 0 is a popular number to look for answers. Will it work?
10 - 0 + 120 = 0 That doesn't work either.
There is no number you could pick that that would give you anything but 10 + 120 = 0
B <<<<<< No Solution
Answer:
Step-by-step explanation:
