Question

Solve$5x+9=5+3x$and check your result.

Answer 1

Step 1: Find the value of $x$

Given : $5x+9=5+3x$

$$\begin{gathered} \Rightarrow 5x–3x+9=5 \\ \Rightarrow 2x+9=5 \\ \Rightarrow 2x=5–9 \\ \Rightarrow 2x=–4 \\ \Rightarrow x=–2 \end{gathered}$$

The value of $x$ is$–2.$

Step 2: Check the solution.

Put $x=–2$in the given equation,

$\Rightarrow$$5(-2)+9=5+3(-2)$

$\Rightarrow$ $–10+9=5–6$

$\Rightarrow$ $–1=–1$

Hence proved $x=–2$ is the correct answer.
