Answer:
[tex]x=2\dfrac{2}{3}\ yards[/tex]
Step-by-step explanation:
Let x yards be the amount of yellow fabric Emma buys.
Emma buys
The total of blue fabric and yellow fabric is
[tex]3\dfrac{2}{3}+x\ yards[/tex]
The total is the same, so
[tex]3\dfrac{2}{3}+x=5\dfrac{1}{3}[/tex]
Solve this equation. Use addition property of equality:
[tex]3\dfrac{2}{3}+x-3\dfrac{2}{3}=5\dfrac{1}{3}-2\dfrac{2}{3}\\ \\x=3\dfrac{1}{3}-\dfrac{2}{3}\\ \\x=3-\dfrac{1}{3}\\ \\x=2\dfrac{2}{3}\ yards[/tex]
