Question

Solve -(2x + 4) = 18.

Answer 1

-(2x+4)= 18

Divide -

2x+4= -18

Subtract 4

2x= -22

Divide 2

x= -11

-(2(-11)+4)= 18

18= 18

Answer 2

Answer:

x=-11

Step-by-step explanation:

For the given equation:

                                   $-(2x + 4) = 18$

Opening the brackets of L.H.S will change sign inside the bracket as the negative sign is outside the bracket

                                     $-2x-4=18$

Now, making the coefficients of 'x' to one side, to find the value of 'x'

                                          $-2x=18+4\\x=22/-2\\x=-11$

So, for the given equation the value of x is -11.
