# Maths ..equation

posted by .

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 !!!

• Maths ..equation -

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
