From the problem below what is the expression from clue 1?

Mrs. Johnson told her class she was thinking of two numbers. She gave them two clues.

Clue 1: The larger number is 2 less than 6 times the smaller number.

Clue 2: The larger number is 19 more than 3 times the smaller number.

Write an equation that can be used to determine the two numbers Mrs. Johnson was thinking.

• y = 2 - 6x

• y = 3x - 19

• y = 3x + 19

• y = 2x - 6
