Veronica loves to collect insects. She has one more than twice as many ladybugs as spiders. She has four less giant mosquitoes than spiders. If Veronica has 61 insects altogether, how many ladybugs does she have.

let spiders = x

ladybug = 2x+1

giant mosquitoes = x-4

total = x+2x+1+x-4

=> 4x - 3 = 61

=> 4x = 64

=> x = 16

spiders = 16

ladybug = 33

giant mosquitoes = 12
