7-(4x+3)=16?

7-4x-3=16

7-3-16=4x

-12=4x

therefore x= -3

7 - (4x + 3) = 16
4x + 3 = - 9
4x = - 12
x = - 3

Answer: x = - 3

Proof:
7 - (4[- 3] + 3) = 16
7 - (- 12 + 3) = 16
7 - (- 9) = 16
7 + 9 = 16

7 - 4x - 3 = 16
4 - 4x = 16
- 4x = 12
x = - 3

7 - 4x - 3 = 16
-4x + 4 = 16
-4x = 16 - 4
-4x = 12
-x = 12/4
x = -3

7 - (4x + 3) = 16
7 - 4x - 3 = 16
-4x = 16 - 7 + 3
-4x = 12
x = 12/-4
x = -3

I am extremely bad at math........7-(4x+3)=16
7-3X4=16 :)

LOL i knew i wasn't going to get it right LMAO

7-16=4x+3
-9=4x+3
4x=-9-3
4x=-12
x=-12/4
x=-3

After distributing your negative, you have
7-4x-3 = 16
-4x-4=16
-4x=12
x= -3

7-4x-3-16=0
-4x=12
x=-3

7-4x-3=16
7-3-16=4x
-12=4x
x=-3

I hope this can be useful
