kvasek [131]

Let, number of spiders = x
number of insects = y

6x + 8y = 36

remember, legs can't be in fraction or decimal.

So, only (3, 2) fits with that.

So, there are 3 spiders & 2 insects in his collection.

Hope this helps!

Step-by-step explanation:

Linear equations

Sometimes we need to know the value of a variable in a given equation and that variable is given as a polynomial of degree 1. Solving for that variable means isolating it and replacing the other known values

Steven was 7 years old eight and one-half years ago. If we call x as the actual age of Steven, his age eight and one-half years ago was

$x-8\frac{1}{2}$

We know he was 7 years old then, so

$x-8\frac{1}{2}=7$

We need to know his actual age, so let's solve for x, adding $8\frac{1}{2}$ to each side of the equation

$x-8\frac{1}{2}+8\frac{1}{2}=7+8\frac{1}{2}$

Simplifying

$x=15\frac{1}{2}$

Steven is 15 and one half years old now
