Answer:
12x
Step-by-step explanation:
We require the lowest common multiple of 4x, 3 and 2x
the lowest common multiple of 4, 3 and 2 is 12
the lowest common multiple of x and x is x
Combining the two gives lowest common multiple of 12x
Multiplying through by 12x gives
72x - 9 + 4x = 6 + 60x ← no fractions
