-(x + 3) = -8
x + 3 = 8
x = 5

Step 1 -- multiply both sides by -4,

(x + 3) = 8

x + 3 = 8

Step 2 -- subtract 3 from both sides of the equation

x + 3 - 3 = 8 - 3

x = 8 - 3

x = 5

Hope this helps.

(1/4) (x + 3) = 2
x + 3 = 8
x = 5

-1/4(x + 3) = -2

Multiply everything by 4 to get rid of that fraction:

-(x + 3) = -2*4
-(x + 3) = -8

Expand:

-x - 3 = -8

Move the -3 to the other side through addition:

-x = -8 + 3
-x = -5

x = 5

(-1/4)(x + 3) = -2
-(x + 3)/4 = -2
-(x + 3) = 4(-2)
-x - 3 = -8
-x = -8 + 3
-x = -5
x = -5/-1
x = 5

Hi, this is Robinka. The solution of your problem goes like this:
=>
Here,
- 1/4 ( x + 3 ) = - 2

or, -1 = - 8(x + 3)

or, -1 = -8x - 24

or, 8x + 24 -1 = 0

or, 8x + 24 = 0

or, 8 (x +3) = 0

or, x + 3 = 8

or, x = 8 - 3

or, x = 5

Therefore, x = 5

-1/4(x+3) = -2

x+ 3 = -2/-(1/4)

x+3 = 8

x = 5

divide by -1/4 bs x+3=8

-3bs x=5
2008-07-16 7:56 am
-1/4(x + 3) = -2

-1/4x -3/4 = -2
-1/4x = -2 + 3/4
-1/4x = -5/4
x = 5 by multiplying both sides by -4/1

x +3 =8

x=5
