Answer:
x = 12 / 7
x = 1 5/7
Step-by-step explanation:
To solve the given formula, we must make use of the concept of LOWEST COMMON MULTIPLE. (LCM)
The LCM of 4 and 3 is 12
Since the LCM of the denominator is 12, we Multiply through by 12
Therefore:
(12) * x / 4. (12) * x / 3. = 12 * 1
3x + 4x = 12
7x = 12
Divide through by 7 to make x the subject of the expression.
7x/7 = 12/7
x = 12 / 7
To simplify further, x = 1 5/7
