Question

Solve the following:

$10x–5–7x=5x+15–8$

Answer 1

Compute the required value:

$$\begin{gathered} 10x–5–7x=5x+15–8 \\ 10x–5–7x=5x+15–8 \\ 3x–5=5x+7 \end{gathered}$$

On rearranging the terms and combining like terms we get

$$\begin{gathered} \Rightarrow 3x–5x=7+5 \\ \Rightarrow –2x=12 \\ \Rightarrow x=\frac{-12}{2} \\ \Rightarrow x=–6 \end{gathered}$$

Hence, the value of $x$is $-6$.
