Answer: x = -2 2x
Step-by-step explanation:
3[-x + (2x + 1)] = x - 1
3 [ -x + 2x + 1] = x - 1
-3x + 6 + 3 = x - 1
Collecting like terms, we have:
-3x + 6x - x = - 1 - 3
2x = -4
Divide both sides by 2, we have
x = -4/2 = -2
Answer:
x=-2
3[-x + (2x + 1)] = x – 1
Remove inside parentheses:
3[-x + 2x + 1] = x – 1
Collect like terms:
3(x+1)=x-1
Multiply parentheses by 3:
3x + 3= x - 1
Move terms:
3x - 3 = x - 1
2x = -1 - 3
Calculate:
DIvide both sides by 2:
x = -2
Solution:
