3/(x + 3) = - 8
- 8x - 24 = 3
8x = - 27
x = - 27/8
Answer: x = - 27/8
Proof:
3/(- 27/8 + 3) = - 8
3/(- 27/8 + 24/8) = - 8
3/(- 3/8) = - 8
3(- 8/3) = - 8
- 8 = - 8
- 8x - 24 = 3
8x = - 27
x = - 27/8
Answer: x = - 27/8
Proof:
3/(- 27/8 + 3) = - 8
3/(- 27/8 + 24/8) = - 8
3/(- 3/8) = - 8
3(- 8/3) = - 8
- 8 = - 8

yes, i can help you :P
first, multiply both sides by (x+3)
so, 3= -8(x+3)
are u with me?
and den expand the right side
3= -8x -24
den, minus 3 from both sides
0 = -8x-27
den add 8x on both sides
8x=-27
den divide by 8 on both sides
x= -27/8
hope this helps :P np

3 / (x+3) = -8
move x+3 to RHS
i.e. 3 = -8 (x+3)
expand RHS
i.e. 3 = -8x -24
move 24 to LHS
27 = -8x
x = -27/8
i think.. ^o)
move x+3 to RHS
i.e. 3 = -8 (x+3)
expand RHS
i.e. 3 = -8x -24
move 24 to LHS
27 = -8x
x = -27/8

3/(x+3)=-8
3= -8*(x+3)
3= -8x -24
8x= -3-24
8x= -27
x= -27/8 (ans)
3= -8*(x+3)
3= -8x -24
8x= -3-24
8x= -27
x= -27/8 (ans)

3/(x+3) = -8
Multiply both sides by x+3 to get rid of the denominator.
3 = -8(x+3)
Expand and simplify the brackets on the right. Remember to apply the negative to each term inside the brackets.
3 = -8x - 24
Move all terms with x to the left and all other terms to the right. Remember to switch signs as you switch sides.
8x = -24 - 3 = -27
Divide both sides by 8 to get x on its own.
x = -27/8 = -3.375
Multiply both sides by x+3 to get rid of the denominator.
3 = -8(x+3)

3 = -8x - 24
Move all terms with x to the left and all other terms to the right. Remember to switch signs as you switch sides.
8x = -24 - 3 = -27
Divide both sides by 8 to get x on its own.
x = -27/8 = -3.375

That's -8x - 24 = 3, or, 8x = -27, then x = -(27/8)

3 divided by X+3 = -8
3 / (X+3) = -8
3 = (-8) * (X+3)
3 = -8X - 24
3 + 24 = -8X
27 = -8X
X = -(27/8)
ANSWER: X = -(27/8)
3 / (X+3) = -8
3 = (-8) * (X+3)
3 = -8X - 24
3 + 24 = -8X
27 = -8X
X = -(27/8)
ANSWER: X = -(27/8)

3/(x + 3) = -8
Multiply both sides by (x + 3) to get rid of the denominator
3/(x + 3) * (x + 3) = -8 * (x + 3)
3 = -8(x + 3)
3 = -8x - 24
Add 24 to each side of the equation
3 + 24 = -8x - 24 + 24
Combine like terms:
3 + 24 = 27
-24 + 24 = 0
27 = -8x or
-8x = 27
Divide each side by -8
-8x/-8 = 27/-8
x = -3.375
Multiply both sides by (x + 3) to get rid of the denominator
3/(x + 3) * (x + 3) = -8 * (x + 3)
3 = -8(x + 3)
3 = -8x - 24
Add 24 to each side of the equation
3 + 24 = -8x - 24 + 24
Combine like terms:
3 + 24 = 27
-24 + 24 = 0
27 = -8x or
-8x = 27
Divide each side by -8
-8x/-8 = 27/-8
x = -3.375

This is actually just a one step equation. To solve this you have to do the opposite of what is being done. The goal is to isolate, or get the x by itself. Since the x is being divided by 6 you have to do the opposite of that and multiply by 6. What you do to one side you have to do to the other. So multiply 8/3 by 6 and that will be your answer.

3/x+3=-8
3=-8x-24
-8x=27,x=27/8
3=-8x-24
-8x=27,x=27/8
