Catherine is using a spool of yarn to knit some items. She uses 14 yards of yarn to knit a scarf. The 3 8 number of yards of yarn she uses to knit a hat is 3 yards less than she uses to knit a scarf. How many 1 4 total yards of yarn does Catherine use to knit a scarf and a hat?

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

answer: the answer is e
