To Find the least common denominator you have to find the multiples of each number

multiple means the product of each factor

so the multiples of 4 would be 4 8 12 16 20

you want to name at least five multiples but if there are not the same multiples you might have to list more

the multiples of 5 would be 5 10 15 20

then I can stop there because I have found two of the same multiples

so now we have our least common denominator which is 20

HOPE THIS HELPS!!!

Using elimination to solving systems of linear equations how would you solve

Amiraneli [1.4K]

12x+y=10 -----> 12x + y = 10
-3=3x+3y ------> -12x - 12y = 12 (multiplied by -4)
-11y = 22
y= -2

12x - 2 = 10
x = 1
