Algebra- write the digits that make each equation true.

__ 3 - 2 __ = 71

5__ - __ 1 = 14

78 - __ 5 = 4 __

1) 9,2

2) 5,4

3) 3,3                    

Step-by-step explanation:

We have to fill the digits in order to make the equation true:

1) The firs digit should be such that when 2 is subtracted it gives 7. Thus, the digit is 9.

The digit in second blank should be such that when subtracted from 3 it gives 1. Thus, the digit is 2.

2) The second digit in first number should be such that when 1 is subtracted from it, gives 4. Thus, the digit is 5.

The digit in second blank should be such that when subtracted from 5 it gives 1. Thus, the digit is 4.

3) The first digit in second blank should be such that when subtracted from 7 it gives 4. Thus, the digit is 3.

The digit in second blank should be 5 subtracted from 8. Thus, the digit is 3.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
