Problema Solution
eight times a number added to -9, subtracted from twice the sum of eight times the number and 9
Answer provided by our tutors
let 'n' represent the number
"eight times a number added to -9" is "(8n-9)"
"twice the sum of eight times the number and 9" is "2(8n+9)"
so we have:
2(8n+9) - (8n-9)
which simplifies to:
8n+27
