Question

( 13 / 4 - y x 2 / 3 ) x3 = 4

 

Answer 1

\(\left(\frac{13}{4}-y\cdot2\right)\cdot3=4\)

\(\frac{13}{4}-y\cdot2=\frac{4}{3}\)

\(y\cdot2=\frac{13}{4}-\frac{4}{3}\)

\(y\cdot2=\frac{39}{12}-\frac{16}{12}\)

\(y\cdot2=\frac{23}{12}\)

\(y=\frac{23}{12}:2\)

\(y=\frac{23}{12}\cdot\frac{1}{2}\)

\(y=\frac{23}{24}\)

Answer 2

\(\left(\frac{13}{4}-\frac{2}{3}y\right).3=4\)

\(\frac{39}{4}-2y=4\)

\(2y=\frac{39}{4}-4\)

\(2y=\frac{23}{4}\)

\(y=\frac{23}{8}\)
