What two numbers add. to twelve but equal 5

-- Two numbers that add to 12 can be

1 and 11
2 and 10
3 and 9
4 and 8
5 and 7
6 and 6

-- There are not two numbers that equal 5.
There is only one.
It is   5  .
 

Given: 1.18x + 4.34 = 8.67
Work:
-First, get the 1.18x alone
1.18x + 4.34 = 8.67
          - 4.34 = -4.34
      1.18x = 4.33
-Next, you have to divide both sides by 1.18
1.18x = 4.33
x = 3.66 (Round to the nearest TENTH) --> x = 3.7
x = 3.7

I hope this helps!
