Answer 2

• As per the data given in the answer, we have to determine the value of $5x.$

       Given data:- $\Rightarrow 2x+10=5x-20.$

       To find the value of $5x$ =?

       Solution:-

• Firstly, we will observe the linear equation and identify the variables and constant.
• Then, we will remove the brackets and shift all terms containing variables on LHS and constant on RHS.
• After that, we divide both terms with a coefficient of variables.

       Therefore,

        $\Rightarrow 2x+10=5x-20\\\Rightarrow 2x-5x=-20-10\\\Rightarrow -3x=-30 \\\Rightarrow x=10.$

       So, $\Rightarrow 5x=5\times10=50.$

       Hence, the value will be $50.$
