Question

12x=50x-20

Answer 1

i get everything except why we divide by 2 at the end

Answer 2

12x=50x-20
20+12x=50x
20=50x-12x
20=38x
x=20/38=10/19

you don't

Answer 4

collect the similar terms then solve it

Answer 5

12x=50x-20
-50x+12=-20
-38/-38 = -20/-38
x= 20/38 divide by 2 = 10/19

Answer 6

You divide each component by 2 to reduce the fraction.

Answer 7

okay thanks , do you always have to do that when you get these type of questions?

Answer 8

whenever you have a fraction, you should always try to reduce it


in the case of 20/38, the GCF of 20 and 38 is 2. So this means that you can reduce and you do so by dividing each component by this GCF 2.
