Least common multiple 6 and 9

Step-by-step explanation:

draw a line and write six and nine now look for number that will divide them

till it reaches one

the first number is two which will.divide six three times

since two can't divide nine we leave it

making three and nine

two can't go in anyone so we use three

three in three once

making one and three

and three in three

making both one

the essence of lcm is to divide the number till it stops at one

thank you

-8 = n

Step-by-step explanation:

5n - 4 = 4 + 6n

Subtract 5n from each side

5n-5n - 4 = 4 + 6n-5n

-4 = 4 +n

Subtract 4

-4-4 = n

-8 = n
