\[\large \color{royalblue}{y=3}\] \[\large 6\cdot\color{royalblue}{y} \qquad=\qquad 6\cdot\color{royalblue}{3} \qquad = \qquad ?\]

zepdrix (zepdrix):

Does the math and color show up alright? Or is it just a bunch of ugly messy code? If you're using Internet Explorer then it won't show up correctly.

yes it shows up alright thankyou

OpenStudy (anonymous):

but i cant find the anwswer

zepdrix (zepdrix):

oh ok :) just confused by the concept? y is equivalent to 3. So in our expression 6y (which is 6 times y), we can replace the y with 3. Which changes our expression to 6 times 3. Do you understand how to finish the multiplication?

OpenStudy (anonymous):

no, im sorry

OpenStudy (anonymous):

thankyou for your help:)
