Answer 2

Given:

We have given an equation which is as 10(x-4)+2(x-5)-5(x+6)=0.

To Find:

We have to simplify the given equation for the value of x?

Step-by-step explanation:

• We have given an algebric equation which is as follows
• 10(x-4)+2(x-5)-5(x+6)=0.
• For simplifying the given equation we need to know the rule of BODMAS which is used in the algebraic equations to solve them.

• The rule of BODMAS said that for simplifying the equation we will do the brackets simplification first of all then we proceeded to division
• First of all we are solving the brackets of the given equation by multiplying the terms

        $10x-40+2x-10-5x-30=0$

• Now, we take the like terms together and simplify them as

         $10x+2x-5x-40-10-30=0$

• Now we do the addition and subtraction in equation written above

       $12x-5x-80=0\\7x=80\\x=\frac{80}{7}$

Hence, the value of x is $\frac{80}{7}$
