Question

HELPPPPPPP MEEEEE BUT PUT THE CORRECT ANSWER

Answer 1

Answer:

$\sf 3\left[-x+\left(2x+1\right)\right]=x-1$

$\sf 3\left(-x+2x+1\right)=x-1$

Combine like terms:

$\sf -x+2x=x$

$\sf 3\left(x+1\right)=x-1$

Expand:

$\sf 3x+3=x-1$

Subtract 3 from both sides:

$\sf 3x+3-3=x-1-3$

$\sf 3x=x-4$

Subtract x from both sides:

$\sf 3x-x=x-4-x$

$\sf 2x=-4$

Divide both sides by 2:

$\sf \cfrac{2x}{2}=\cfrac{-4}{2}$

$\boxed{\boxed{ \sf x=-2}}$
