-6(2x+1)=4x+10 .... Start with the given equation
-12x-6=4x+10 .... Distribute
-12x=4x+10+6 .... Add 6 to both sides
-12x-4x=10+6 .... Subtract 4x from both sides
-16x=10+6 .... Combine like terms on the left side
-16x=16 .... Combine like terms on the right side
x=(16)/(-16) .... Divide both sides by -16 to isolate x
x= -1 .... Divide
--------------------------------------------------------------
Answer:
So our answer is x= -1

-6(2x+1)=4x+10
-6·2x - 6·1 = 4x + 10
-12x - 6 = 4x + 10
-16x = 16
x = -1

-6 (2x+1) = 4x +10
multiply out
-12x - 6 = 4x + 10
plus 12x
-6 = 16x + 10
minus 10
-16 = 16x
divide 16
-1 = x
Yo! It's C, not A. lol your winding us up!! hehe :)

-6(2x+1) = 4x + 10
-12x - 6 = 4x + 10
-12x = 4x + 16
-12x - 4x = 16
-16x = 16
x = 16/-16
x = -1
â´the answer is C) -1

- 6(2x + 1) = 4x + 10
- 3(2x + 1) = 2x + 5
- 6x - 3 = 2x + 5
8x = - 8
x = - 1
Answer: x = - 1
Proof:
- 6(2[- 1] + 1 = 4(- 1) + 10
- 6(- 2 + 1) = - 4 + 10
- 6(- 1) = 6
6 = 6

distribute:
-12x-6=4x+10
add -12x to both sides:
-6-10=4x+12x
subtract and add
-16=16x
divide by 16
x=-1
