Question 93218: I need help in solving this equation
2(x+3) = -4(x+1)
This is how I started:
2x+6 = -4x - 4
2x + 6-6 = -4x-4-6
2x = -4x - 2
2x + 4x = -4x+4x-2
6x = 2
(my answer is incorrect)

2%28x%2B3%29+=+-4%28x%2B1%29

2x%2B6+=+-4x-4 Distribute


2x=-4x-4-6 Subtract 6 from both sides


2x%2B4x=-4-6 Add 4x to both sides



6+x=-4-6 Combine like terms 2+x and 4+x on the left side to get 6+x




6+x=-10 Combine like terms -6 and -4 on the right side to get -10 (this is where you went wrong I believe.)





x=%28-10%29%2F%286%29 Now divide both sides by 6 to isolate and solve for x


x=+-5+%2F+3 Reduce



So the approximate answer is

x=-1.66666666666667

which rounds to

x=-1.667
