Answer:
No
Step-by-step explanation:
This is because the definition of absolute value is the number of units or points from zero on a number line. The regular answer of 3-7 would be -4. But the absolute value of -4 is 4 because it is just regularly 4 digits away from zero on a number line. Make sense?
Answer:
The correct answer is Option 4: 12
Step-by-step explanation:
Given equation is:

We have to find a number that is common multiple of all the denominators or least common divisor
So to find the LCM
The numbers in denominator are: 4,3,2
So,

It can clearly be seen that 12 is the LCM of all three numbers so the equation will be multiplied with 12 to eliminate the fractions.

Hence,
The correct answer is Option 4: 12
