But you got the class notes from a friend, and you have studied the examples in your book, right?

Find three consecutive even integers such that 3 times the sum of the [first?] two is 48 less than the third.
i) Pick a variable for "the first" integer. How much bigger is "the next" (that is, "the second") even integer?
ii) Use this information to write an expression, in terms of the variable, for "the third" number. Then continue on to find an expression for the third number.
iii) From the variable and the expressions, create an expression for "the sum of the first two". Simplify. Multiply by 3.
iv) Create another expression for "forty-eight less than" "the third". Simplify.
v) Set (iii) equal to (iv). Solve the equation.
vi) Back-solve for the other two numbers. Remember to check your solution.
If you get stuck, please reply showing how far you have gotten. Thank you.
