Question

Kyra saw 4 times as many birds as squirrels in her backyard. She saw a total of 15 birds and squirrels. How many birds did Kyra see in her backyard?

Answer 1

This is an exercise in formulating the equation from real life scenario.
if b = no of birds and s = no of squirrels then you need to write 2 equations
"Kyra saw 4 times as many birds as squirrels in her backyard"
1) write this as an equation using s and b
" She saw a total of 15 birds and squirrels"
2) Write this as equation in s and b

You now have 2 simultaneous equations using s and b - so solve using whatever method you have for simultaneous equations.
