Question

If 6x-1=29, what is the value of x2+x

Answer 1

We are given

`6x-1=29`

Therefore the value of x can be gotten by simplifying the above equation

`\begin{gathered} 6x=29+1 \\ 6x=30 \\ x=(30)/(6) \\ x=5 \end{gathered}`

Given that x is 5, we can proceed to find the value of the expression.

`\begin{gathered} x^2+x \\ \Rightarrow(5)^2+5 \\ \Rightarrow25+5 \\ \Rightarrow30 \end{gathered}`

This implies that

`x^2+2\Rightarrow30`
