Maths ..equation
posted by leo .
Is this right please ....
3( y  4 )  2 ( 5  6y )
= 3 x y = 3y, 3 x  4 =  12
2 x 5 = 10,  2 x 6y =  12y
Therefore, 2y 12 10 12y
If I am wrong can you advise where I am going wrong .Thanks !!!

You should not write your solutions in bits and pieces, besides some of your steps are not correct.
Here is how it should look:
3( y  4 )  2 ( 5  6y )
= 3y  12  10 + 12y
=15y  22
