Solve the equation for the specified variable for a:
2a−7b/3=9

a = 13.5 + 3.5b

Step-by-step explanation:

Step 1:

2a - 7b/3 = 9          Equation

Step 2:

2a - 7b = 27          Multiply 3 on both sides

Step 3:

2a = 27 + 7b     Add 7b on both sides

a = 13.5 + 3.5b        Divide 2 on both sides

step-by-step explanation:

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.
