Question

Fill in blank (18+9)+4=18+(9+ )

Answer 1

Answer:

x = 0

Step-by-step explanation:

Lets make the only unknown number x.

So it would be ( 18 + 9 ) + 4 = 18 + ( 9 + x )

Solve the brackets first.

( 18 + 9 ) + 4 = 27 + 4

                   = 31

18 + ( 9 + x ) = 18 + ( 9 + x )

Which means that :

27 =  18 + ( 9 + x )

Lets find the x.

27 = 18 + ( 9 + x )

27 ( -18 ) = 18 + ( 9 + x ) ( -18 )

9 = ( 9 + x )

9 ( -9 ) = ( 9 + x ) ( -9 )

0 = x

x = 0

So, the value of X is 0
