According to your question the weight of 12 apples and the basket = 3105.
So,numerically=>12x+y=3105 so the another equation would be => 7x+y=1980=>y=1980-7x
Now,substitute this value of y in the first equation=>
12x+y=3105 => 12x+1980-7x=3105 =>5x=1125=>x=225
x is the weight of the apple and y is the weight of the basket.Now put the value of x in any equation containing y...
7(225)+y=1980
1,575+y=1980
y = 1980 - 1575 = 405 grams is the weight of the basket.
