1/4(24x+12)=6(x+1/2)
forsale [732]

Answer:

The final answer cannot be decided

Step-by-step explanation:

Since 1/4(24x+12)=6(x+1/2)

This can also be written as

24x+12/4=6(x+1/2)

So let's open the bracket from the right side and also solving using the LCM

24x+12/4=6(2x+1/2)

Open the bracket

24x+12/4=3(2x+1)

24x+12/4=6x+3

Cross multiply

24x+12=4(6x+3)

24x+12=24x+12

Collect like terms

24x-24x=12-12

0=0

Therefore the final answer cannot be decided
