Question

(a-b)-(b + a) = -2b true or false​

Answer 1

Answer:

Sorting is any process of arranging items systematically, and has two common, yet distinct meanings: ordering: arranging items in a sequence ordered by some criterion; categorizing: grouping items with similar properties.

Answer 2

Given: The equation is$(a-b)-(b + a) = -2b$

We have to find whether the given statement is true or false.

• By using the Bodmas rule, we are solving the above equation.
• As we know that the Bodmas rule is used to remember the order of operations to be followed while solving expressions in mathematics.

Where,

$\begin{array}{l}\mathrm{B}=\text{brackets}\\\mathrm{O}=\text { order of powers or rules } \\\mathrm{D}=\text { division } \\\mathrm{M}=\text { multiplication } \\\mathrm{A}=\text { addition } \\\mathrm{S}=\text { subtraction }\end{array}$

We are solving in the following way:

We have,

$(a-b)-(b + a) = -2b$

Solving the LHS:

$=>(a-b)-(b + a)\\=>a-b-b-a\\=>-2b$

Hence, LHS=RHS

So, the given statement is true.
