Question

tim y 

y x 3/4 + 2/ 5 = 1

Answer 1

y x 3/4 = 1 - 2/5

y x 3/4 = 3/5

y = 3/5 : 3/4

y = 4/5

Answer 2

\(y\times\dfrac{3}{4}+\dfrac{2}{5}=1\)

\(\Leftrightarrow y\times\dfrac{3}{4}=1-\dfrac{2}{5}\)

\(\Leftrightarrow y\times\dfrac{3}{4}=\dfrac{3}{5}\)

\(\Leftrightarrow y=\dfrac{3}{5}:\dfrac{3}{4}\)

\(\Leftrightarrow y=\dfrac{3}{5}\times\dfrac{4}{3}\)

\(\Leftrightarrow y=\dfrac{4}{5}\)

Answer 3

y x \(\dfrac{3}{4}+\dfrac{2}{5}=1\)
y x \(\dfrac{3}{4}=1-\dfrac{2}{5}\)
y x \(\dfrac{3}{4}=\dfrac{3}{5}\)
y\(=\dfrac{3}{5}:\dfrac{3}{4}\)
y\(=\dfrac{4}{5}\)

Answer 4

y x\(\dfrac{3}{4}\)= 1- \(\dfrac{2}{5}\)

y x \(\dfrac{3}{4}\) = \(\dfrac{3}{5}\)

y = \(\dfrac{3}{5}\) : \(\dfrac{3}{4}\)

y = \(\dfrac{4}{5}\)

Answer 5

y x 3/4 = 1 - 2/5

y x 3/4 = 3/5

y = 3/5 : 3/4

y = 4/5
