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.

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
