Explanation:
The complete question is
Jessica has 84.5 yards of fabric to make curtains. She makes 6 identical curtains and has 19.7 of fabric remaining. How many yards of fabric does Jessica use per curtain?
Let
x-------> amount of yards of fabric that Jessica used per curtain
we know that
The length of 6 identical curtains plus the length of the fabric remaining, must be equal to the total yards of fabric'
so
The linear equation that represent this situation is
Solve for x
![6x=84.5-19.7\\6x=64.8\\x=10.8\ yd](https://img.qammunity.org/2021/formulas/mathematics/middle-school/pimdq5g5vfa8tt2sz2dpfeiajl1mmovghu.png)
