Step-by-step explanation:
Answer=10
When rounding to the nearest whole number, we need to look to the number in the tenths place
10.09
If the number is 5 or greater, we round up. If the number is 4 or less, we round down.
The number is 0, so we would round down.
10.09 becomes 10
S1: 7x - 4x - 2 = 6 OK
S2: 3x - 2 = 6 OK
S3: 3x - 2 + 2 = 6 WRONG, correct is 3x - 2 + 2 = 6 + 2

35-15 is 20. and 43-26 is 17. These two are different because you are regrouping in the 2d problem, as in the first, you just subtract.
They are both found by adding all the sides
