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

x=−2 if i could get brainliest that would be great

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(−x+2x+1)=x−1

(3)(−x)+(3)(2x)+(3)(1)=x+−1(Distribute)

−3x+6x+3=x+−1

(−3x+6x)+(3)=x−1(Combine Like Terms)

3x+3=x−1

3x+3=x−1

Step 2: Subtract x from both sides.

3x+3−x=x−1−x

2x+3=−1

Step 3: Subtract 3 from both sides.

2x+3−3=−1−3

2x=−4

Step 4: Divide both sides by 2.

2x/2=−4/2

x=−2

i belive those are the ones that are under 90 degreese.

is there any photos or whatever?
