-(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
-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
