Example
Let:
1st # = x
2nd# = x+ 1
3rd #= x + 2
4th # = x + 3 set of numbers
Then translate a verbal problem into an algebraic equation and solve
For consecutive odd or even integers, also always start with a Let Statement and increment by 2:
Example
Let:
1st # = x
2nd # = x+2
3rd # = x+4
4th # = x+6
Then translate a verbal problem into an algebraic equation and solve
Example
Let:
1st # = x
2nd # = x+2
3rd # = x+4
4th # = x+6
Then translate a verbal problem into an algebraic equation and solve
