Solve 3[-x + (2x+1) ]=x-1

x=-2

Step-by-step explanation:

First, we can use the distributive property on the left side to give us

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

Distributing a second time gives us

-3x+6x+3=x-1

Simplifying the left side gives us

3x+3=x-1

Next, we can subtract x from both sides, giving us

2x+3=-1

Then, we can subtract 3 from both sides, resulting in

2x=-4

Lastly, dividing both sides by 2 gives us

x=-2
