Question

Solve the following:

$5(x–1)–2(x+8)=0$

Answer 1

Compute the required value:

$5(x–1)–2(x+8)=0$

$$\begin{gathered} \Rightarrow 5x–5–2x–16=0 \\ \Rightarrow 3x–21=0 \end{gathered}$$

On rearranging the terms and combining like terms we get,

$$\begin{gathered} \Rightarrow 3x=21 \\ \Rightarrow x=21/3 \\ \Rightarrow x=7 \end{gathered}$$

Hence,the value of $x$ is $7$
