Add the following algebraic expressions.
a) $ x+5 $ and $ x+3 $
b) $ 3 x+4 $ and $ 4 x+9 $
c) $ 5 y-2 $ and $ 2 y+7 $ d) $ 8 y-3 $ and $ 5 y-6 $
To do:
We have to add the given algebraic expressions.
Solution:
a) \( x+5 \) and \( x+3 \)
$(x+5)+(x+3)=(x+x)+(5+3)$
$=2x+8$
b) \( 3 x+4 \) and \( 4 x+9 \)
$(3x+4)+(4x+9)=(3x+4x)+(4+9)$
$=7x+13$
c) \( 5 y-2 \) and \( 2 y+7 \)
$(5y-2)+(2y+7)=(5y+2y)+(-2+7)$
$=7y+5$
d) \( 8 y-3 \) and \( 5 y-6 \)
$(8y-3)+(5y-6)=(8y+5y)+(-3-6)$
$=13y-9$
