A = number of ants
w = number of worms
There are 20 more ants than worms.
⇒ a - 20 = w
There are 80 insects.
⇒ a + w = 80
-----------------------------------
Solve for a and w :
-----------------------------------
a -20 = w -------------- (1)
a + w = 80 -------------- (2)
Substitute equation (1) into (2) :
a + (a - 20) = 80
a + a - 20 = 80
2a - 20 = 80 // combine like terms
2a = 100 // add 20 to both sides
a = 50 // divide by 2 on both sides
-----------------------------------
Sub a = 30 into equation (1) :
-----------------------------------
a - 20 = w
50 - 20 = w
w = 30
-----------------------------------
Find ants and worms :
-----------------------------------
ants = a = 50
worms = w = 30
----------------------------------------------------------------------
Answer: There are 50 ants and 30 worms.
