Answer:
x=-2
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
