The eggs of the golden goose is an illustration of linear equation
From the question, we have the following equations
b = w + 3
w + b = 13
Substitute w + 3 for b in w + b = 13
w + w + 3 = 13
This gives
2w + 3 =13
Subtract 3 from both sides
2w = 10
Divide both sides by 2
w = 5
Recall that:
b = w + 3
So, we have:
b = 5 + 3
b = 8
Hence, 5 were white eggs and 8 were brown eggs
