Answer 1

The subtraction property of equality states that if you have an equation of the form \(a + b = c\), you can subtract \(b\) from both sides to isolate \(a\). This property can be applied to equations where a quantity is being added to a variable, allowing you to solve for that variable by subtracting the same quantity from both sides.

Here are the equations from your list that can be solved using the subtraction property of equality:

1. **9 + y = 11** (You can subtract 9 from both sides to solve for y)
2. **h + 4 = 12** (You can subtract 4 from both sides to solve for h)
3. **x - 3 = 17** (This also uses the subtraction property; you can add 3 to both sides to solve for x)

Among the other given options:

- **b - 13 = 26** can also be solved using the addition property (by adding 13), but it does involve subtraction too.
- **5y = 20** involves division, not directly related to the subtraction property for isolating y.
- **56 = x + 7** can also be solved using the subtraction property by subtracting 7 from both sides.

Ultimately, the three that definitely apply for direct use of the subtraction property are:
1. **9 + y = 11**
2. **h + 4 = 12**
3. **x - 3 = 17**

You can check these selections using the feature you mentioned.
