Just add. 6.5+12.3= 18.8 then subtract 20-18.8= 1.2. She needs 1.2 mores yards
Your final equation would be 3(x+1)= 3x+3 because if you do 3 times x you get 3x so if you do 3 times 1 you get 3 making the equation have infinite solutions.
The final answer is: 3(x+1)= 3x+3 for an infinite number of solutions.
