Help please Can you clear fractions in an equation by multiplying each side by a common denominator other than the LCD? Give an
example to explain your reasoning.
1 answer:
Yes here is an example:_
x/4 + 5/6 = 2
The LCD of 4 and 6 is 12 but we can also multiply through by 24 to clear the fractions:-
x/4 * 24 + 5/6 * 24 = 2 + 24
6x + 20 = 40
This will give us the same result if we multiplied through by 12.

2(4z-9-11)=166-46
8z-18-22=120
8z-40=120
Add 40 from both side
8z-40+40=120+40
8z=160
Divided 8 from both side
8z/8=160/8
z=20. Hope it help!
