Can you please help me on this question m+2m-6=-12+2m

m= -6

Step-by-step explanation:

1st step: cancel 2m on both sides  

m-6=-12

2nd step: Add 6 to both sides

m= -12+6

3rd Step Simplify -12+6 to -6

m= -6

p║q hence proved.

step-by-step explanation:

in the question given parameters are line l║m and ∠1 = ∠3

and we have to prove p║q.

since ∠1 = ∠3 (given)

opposite angle of ∠1 = ∠2 (alternate interior angles)

therefore ∠2 = ∠3 (transitive property)

∠2 = ∠3 are congruent when lines p and q are parallel and lines l and m are transverse.

therefore p║q.  

hence proved.
