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

Sagot :

Answer:

x=−2

Step-by-step explanation:

Simplify both sides of the equation.

3(−x+2x+1)=x−1

Distribute

(3)(−x)+(3)(2x)+(3)(1)=x+−1

−3x+6x+3=x+−1

Combine Like Terms

(−3x+6x)+(3)=x−1

3x+3=x−1

3x+3=x−1

Subtract x from both sides.

3x+3−x=x−1−x

2x+3=−1

Subtract 3 from both sides.

2x+3−3=−1−3

2x=−4

Divide both sides by 2.

2x/2=−4/2

x=-2
