Question

Simplify the given expressions : ( 2a + 3b ) + ( 11a + 9b ) + ( 12a – 15b ) + ( b – 20a )​

Answer 1

SOLUTION

TO SIMPLIFY

The given expressions :

( 2a + 3b ) + ( 11a + 9b ) + ( 12a – 15b ) + ( b – 20a )

EVALUATION

( 2a + 3b ) + ( 11a + 9b ) + ( 12a – 15b ) + ( b – 20a )

= ( 2a + 11a + 12a - 20a ) + ( 3b + 9b - 15b + b)

= ( 2 + 11 + 12 - 20 )a + ( 3 + 9 - 15 + 1 )b

$= \sf{5a + ( - 2)b}$

$= \sf{5a - 2b}$
