Answer:

Statement                                                Reason

\frac{1}{2}(10m-14)+9=12                       Given

5m-7+9=12                                Distributive property

5m+2=12                                   Combine like terms

5m=10                                       Subtraction property of equality

m=2                                           Division property of equality

Step-by-step explanation:

The given equation is

\frac{1}{2}(10m-14)+9=12

We need to prove m=2.

\frac{1}{2}(10m)+\frac{1}{2}(-14)+9=12                          (Distributive property)

5m-7+9=12

5m+2=12                               ( Combine like terms)

Subtract 2 from both sides.

5m=12-2                     (Subtraction property of equality)

5m=10

Divide both sides by 5.

\frac{5m}{5}=\frac{10}{5}

m=2                       (Division property of equality)

Hence proved.

1. \frac{1}{2}(10m - 14) + 9 = 12        1. Given

2.    5m - 7 + 9 = 12          2. Distributive Property

3.    5m      + 2 = 12          3. Simplify (added like terms)

4.    5m            = 10          4. Subtraction Property of Equality

5.      m            =  2           5. Division Property of Equality
