The cost of fencing (C)
The cost is calculated as:
Let:
So, we have:
<em>The question cannot be solved further since the dimension of the fence is not given</em>
<em>If you know the dimension, calculate the fence perimeter and substitute the value for x</em>
Answer/Step-by-step explanation:
4x - 7 = -2x + 12 (Given)
Add 2x to both sides
4x - 7 + 2x = -2x + 12 + 2x (Addition property of equality)
6x - 7 = 12 (Simplication)
Add 7 to both sides
6x - 7 + 7 = 12 + 7 (Addition property of equality)
6x = 19 (Simplification)
Divide both sides by 6
(Division property of equality)
