Question

Find the value of n if(9 y - 8) + (y + 5) is equivalent to (n y - 3)?

Answer 1

`(9y-8)+(y+5)=(ny-3)`

First we need to simplify the expression

`10y-3=ny-3`

then we sum the terms with y

`\begin{gathered} 10y-ny=3-3 \\ \end{gathered}`
`y(10-n)=0`

then we need to clear n

`\begin{gathered} 10-n=0 \\ n=10 \end{gathered}`

the value of n=0
