Hey there, 

Lets solve this equation step by step. 

⇒ First of all, Simplify 2x×3y to 6xy 

[tex]6xy-3x^2+7y * 2x-12y[/tex] 

⇒ Now Simplify 7y×2x to 14yx

[tex]6xy-3x^2+14yx-12y[/tex] 

⇒ Gather like terms 

[tex](6xy+14xy)-3x2-12y [/tex] 

⇒ Simplify everything 

[tex]20xy-3x^2-12y[/tex] 

                                        Hence Simplified. 

Okay, so if you have 2x*3y-3y*2+7y*2x-12y, add all your like terms together. If you have a constent, add it to the equation.

4x-2y*2 (<- I think this is my correct answer, haven't done this in a while.)
