Question

2a - 2b - 4 - 5 + a​

Answer 1

Answer:

2a - 2b - 4 - 5 + a

= (2a + a) - 2b - 9 {By applying BODMAS RULE}

= 3a - 2b - 9

Answer 2

$\sf\bold{Given:}$ $\sf{a}$= -1 , $\sf{b}$ -2

= 2a + a - 2b - 4 -5

= 3a - 2b -9

✯ The value of the value of a and b in the equation:-

= (3 × (-1)) - (2 × (-2)) -9

= 3 - (-4) -9

= -3 + 4 -9

= -12 + 4

$\large\mapsto\boxed { \sf \green{-8}} \:$
