Challenge! Ready? What is the solution to the proportion, 3y-8/12= y/5? Show me your work so that I, Lolly, know you are not cheating. THIS IS A PROPORTION; where you cross multiply.

    This is not simple algebra.

    is [3y-8]/12 the left side...

    \[\frac{ 3y-8 }{ 12 }=\frac{ y }{ 5 }\]

    ok, remember to group the numerator if multiple terms...

    so if you multiply both sides by a common denominator... in this case (12*5), you,,, nevermind just do the cross multiply thing 5*(3y-8) = 12*y

    can you distribute the 5 into that parenthesis term ?

    \[\large \sf 15y-40=12y\]\[\large \sf 3y=40\]\[\large \sf y=\frac{40}{3}\] Right?

    Hint: \(\sf \Large\frac{a}{b} = \frac{c}{d} \to ad = bc\) And this question as a challenge, and asking for work seems rather suspicious to me...

    Could you please write this: 3y-8/12= y/5 using the equation button or the draw tool?

    I checked my work, and that's what makes the two sides equal...

    \[\large \sf \frac{3(\frac{40}{3})-8}{12}~=~ \frac{40}{3 \times 5}\] \[\large \sf \frac{40-8}{12}=\frac{40}{15}\]\[\large \sf \frac{32}{12}~=~\frac{40}{15}\]\[\large \frac{8}{3}~=~\frac{8}{3}\]
