Answer 2

To find  : sum of $-2x+9y \ and \ 3x - 7y$

Solution :

• To perform addition of given algebraic expressions we following rules should be followed .

• To add given algebraic expression, we add like terms together

• We arrange given terms in standard from if required .

• Removing parenthesis and changing sign we add given expressions.

                  $(-2x + 9y ) + ( 3x - 7y ) \\= -2x + 9y + 3x - 7y \\= x + 2y$  

Hence, on adding $-2x+9y \ and \ 3x - 7y$ we get sum equal to $x + 2y$.
