b−13=26
b minus 13 is equal to 26

x−3=17
x minus 3 is equal to 17

h+2=54
h plus 2 is equal to 54

Answer 1

The subtraction property of equality states that if you subtract the same number from both sides of an equation, the two sides remain equal.

The equations where the subtraction property of equality would be used to isolate the variable are:

1. **b−13=26** (You would add 13 to both sides to solve for b.)
2. **x−3=17** (You would add 3 to both sides to solve for x.)
3. **h+2=54** (You would subtract 2 from both sides to solve for h.)

The first two equations use subtraction directly, and the last one involves using subtraction through manipulation, even though it seems additive.

Thus, the three equations you would select are:

- b−13=26
- x−3=17
- h+2=54
