x − 9 − 2x + 2 = 1

x = 8

Step-by-step explanation: Solve for the equation x - 9 - 2x + 2 = 1.

Step 1: x - 9 - 2x + 2 = 1

Step 2: x + (-2x) - 9 + 2

Step 3: x - 7 = 1

Step 4: x - 7 + 7 = 1 +7

Step 5: x = 8

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
