5a+10b=5(a+2b)
10+15a-5b=5(2+3a-b)
8z-16x-20t=4( 2z-4x-5t)
10a+20b+30b-40d= 10 ( a+2b+3b-4d)=10( a+5b-4b)
10+15a-5b=5(2+3a-b)
8z-16x-20t=4( 2z-4x-5t)
10a+20b+30b-40d= 10 ( a+2b+3b-4d)=10( a+5b-4b)
5a+10b=5(a+2b)
10+15a-5b=5(2+3a-b)
8z-16x-20t=4(2z-8x-5t)
10a+20b+30b-40d=10(a+2b+3b-4d)
Sper ca te-am ajutat :)
