Answer:

x=32

Step-by-step explanation:

first, you add 64 to both sides and you have:    x2=64

second, you divide 2 on both sides to get x by itself, so 64 divided by 2 is 32

Pens are on sale for 3 pens for $6 Karen bought 3 pens Leo bought 1 pen how much more did Karen spend than Leo
Rasek [7]
If the correlation is correct, then 1 pen would be equal to $2. In this case, karen spent $2 for each pen for a total of 3 pens for $6. If Leo bought 1 pen, he would spend $2. So, $6-$2=$4. Karen spent 4 more dollars than Leo. If this helped, please mark me brainliest, thank you and if you need more help, feel free to message me!
