I cut a long piece of wood into 50cm pieces. I manage to cut w pieces of wood, and there is 20cm left over.

How long was the wood to start with?

Step-by-step explanation:

Given

Length of Pieces = 50cm

Number of Pieces = w

Left over = 20cm

Required

Determine the length of the wood

Start by multiplying the number of pieces by the length of each pieces

Lastly, add the leftover to get the actual length of the wood

Substitute 50w for Result and 20 for Leftover

Hence, the length of the wood is 50w + 20

they can both be solutions depends on the equation
