Question

To solve the linear equation ​, the first step is to multiply each side by the least common denominator of all the fractions in the equation. What is the​ LCD?

Answer 1

Answer:

84

Step-by-step explanation:

The least common denominator of the 7, 6, 12, which are the denominators of the fractions in the given linear equation, is the least expression or number that is divisible by 7, 6, 12.

To find the LCD, express each number as factors of itself as follows:

$7 = 1*7$

$6 = 2*3$

$12 = 2^2*3$

Find the product of the highest terms

The product = LCD = $1*2^2*3*7 = 84$

LCD of 7, 6, 12 = 84
