<h3>Answer: 4x + 42 = 5</h3>
==========================================================
Explanation:
The fractions we want to eliminate are 2/3 and 5/6. The lowest common denominator (LCD) is 6.
If we multiply both sides by the LCD, then we'll cancel out the fractions. This is because
6*(2/3) = (6/1)*(2/3) = (6*2)/(1*3) = 12/3 = 4
6*(5/6) = (6/1)*(5/6) = (6*5)/(1*6) = 30/6 = 5
So in short, the (2/3)x becomes 4x and the 5/6 becomes 5 after we multiply both sides by the LCD 6.
