Bob's pet snake is 10 inches shorter than three times the length of Mary's pet snake. If both their snakes laid together end to end measure 110 inches, how long is Bob's snake? Which equation would NOT solve this problem?

The length of Bob's snake = x = 80 inches

The length of Mary's snake = y = 30 inches

Step-by-step explanation:

Let the length of Bob's snake = x

the length of Mary's snake = y

From the above question:

Bob's pet snake is 10 inches shorter than three times the length of Mary's pet snake.

x = 3 × y - 10

x = 3y - 10

If both their snakes laid together end to end measure 110 inches, how long is Bob's snake?

x + y = 110 inches

Substance 3y - 10 for x

3y - 10 + y = 110

Add 10 to both sides of the Equation

3y + y -10 + 10 = 110 + 10

4y = 120

y = 120/4

y = 30 inches

x + y = 110 inches

x + 30 inches = 110 inches

x = 110 inches - 30 inches

x = 80 inches
