Two birds each have 6 eggs. How many eggs do they have alltogether? 12 eggs.
6 birds are building a nest. If each bird brings 2 sticks for the nest, how many sticks will be in the nest? 12 sticks.
Answer:
-12 and -5
Step-by-step explanation:
a+b=-17
b-a=7
b=7+a
a+7+a=-17
2a+7=-17
2a=-17-7
2a=-24
a=-12
-12+b=-17
b=-17+12
b=-5
so a and b are -12 and -5 respectively
