me thank wot him sae is...
for integers, for all or NE x,y yu selekt the equashun
1265x + 2070y=c will giv yu c=m*115, weer c=integer >=1
him sae in parens, that 1265=mx*115 & 2070=my*115
so yu hav (mx+my)*115
so hart av the statement is ....produkt m*x....anser gotta be integer wen m& x=integer
that statement is true
but me dont no wot yer teech will aksept as proof it be true
