Answer:
m=-7
Step-by-step explanation:
You begin with the equation:
2m-6=4m+8
The first step of this would be to subtract 2m from both sides. This is the subtraction property of equality.
-6=2m+8
The next step would be to subtract 8 from both sides. This is the subtraction property of equality.
-14=2m
Next, divide both sides by 2. This is the division property of equality.
-7=m
The final step would be the symmetric property of equality.
m=-7
Therefore your proof would have the steps:
subtraction property of equality
subtraction property of equality
division property of equality
symmetric property of equality
