Question

Mark was thinking of a number. Mark adds 1.7 to the number, then doubles the result to get an

answer of 42.7. Form an equation with x

Answer 1

2(x + 1.7) = 42.7

Explanation:

• "adds 1.7 to the number" represents x + 1.7
• "then double the result" combined with "adds 1.7 to the number" represents 2(x + 1.7)
• "answer of 42.7" combine with all of the above makes 2(x + 1.7) = 42.7
