Question

Simplify each of the following algebraic expressions by removing grouping symbols $3x-(y-2x)$

Answer 1

Hint: Algebraic equation is formed from variables and constants using different operations.
solve the equation but firstly solve brackets then simplify. The sum of two like terms is a like term with coefficients equal to the sum ( or difference) of coefficients of the two like terms.

Complete step-by-step answer:
Expressions are made up of terms
A term having the same algebraic factors are called like terms.
if terms having the different algebraic factors are called unlike terms.
$3x - \left( {y - 2x} \right)$
simplify, we get
$3x - y + 2x$
Then, same terms is added
$5x - y$
so, it is an unlikely term because both variables are different.

Note: The above answer must be open brackets and know about like and unlike terms when we add (or subtracted) two algebraic expressions, the like terms are added (or subtracted) and the unlike terms are written as they are.Rules and formula in mathematics are written in a concise and general form using algebraic expressions.
