Question

Simplify the expression and find the value if $x=2$

$6x+5\left(x-2\right)$

Answer 1

Given: $6x+5\left(x-2\right)$

Putting $x=2$, in the given expression, we get

$$\begin{gathered} 6x+5\left(x-2\right) \\ =6\left(2\right)+5\left(2-2\right) \\ =12+5\left(0\right) \\ =12 \end{gathered}$$

Hence, the value of $6x+5\left(x-2\right)$ is $12$.
