You must

You must level a rooftop unit on the curb with shims. If you need to shim the unit 13/16” on one side, how many shims will be required if he is given 1/8” and 1/16” shims? Use 10 shims exactly.

Correct answer:

a =  3
b =  7

Step-by-step explanation:


a+b=10
13 = 2•a+b

a+b = 10
2a+b = 13

a = 3
b = 7
