Question

[15+(-11)]+(-9)=_____ +[(-11)+(-9)]

Answer 1

Answer:

15 is to be written in the blank.

Step-by-step explanation:

[ 15 - 11 ] +( -9) = x + [ -11 -9 ]

[ 4 ] - 9 = x + [ -20 ]

4 - 9 = x - 20

- 5 = x - 20

- 5 + 20 = x

15 = x

Answer 2

Answer:

$\huge\bf\red{\boxed{\boxed{\underline{\bigstar{S_OL_UT_IO_N}}}}}$

$\large\bf\blue{→{15+( - 11)}+(-9)=x+{(-11)+(9)}}$

$\large\bf\blue{→4 - 9 = x - 20}$

$\large\bf\blue{→- 5 = x - 20}$

$\large\bf\blue{→x = 20 + 5}$

$\large\bf\blue{→x = 15}$
