Question

2/5(z+1)=y for z

Answer 1

\[\frac{ 2 }{ 5(z+1)} = y\]
\[\frac{ 2 }{5z + 5 } = y\]
\[2 = y (5z + 5)\]
\[\frac{ 2 }{ y } = 5z + 5\]
\[\frac{ 2 }{ y } = 5(z+1)\]
\[\frac{ 2 }{ 5y } = z+1\]
\[\frac{ 2 }{ 5y } -1 = y\]

Answer 2

\[\frac{ 2 }{ 5y } - 1 = z *\] This is the last step. I got it wrong.

Answer 3

ok thanks
