Problem: 18w-21= 15w+3
solve each equation find your answer in the decoder each
time your answer occurs in the decoder write the letter
of the problem above it
18w - 21 = 15w + 3
18w - 21 - 15w = 15w + 3 - 15w
3w - 21 = 3
3w - 21 + 21 = 3 + 21
3w = 24
3w/3 = 24/3
w = 8
Answer: w = 8
The rest will remain a mystery. We have no idea
what the decoder is, or what game this came from.
