Question

| 3 - 2x | = 4x +1

Answer 1

| 3 - 2x | = 4x + 1

3 - 2x = 4x + 1

3 -1 = 2x +4x

2 = 6x

x = 2/6

Answer 2

| 3 - 2x | = 4x + 1

3 - 2x = 4x + 1

3 -1 = 2x +4x

2 = 6x

x = 2/6

Answer 3

- nếu | 3-2x| = 3-2x thì 3-2x \(\ge\)0=) -2x\(\ge\)-3 =) x\(\le\)3/2

- nếu | 3-2x| = -3+2x thì 3-2x< 0=) -2x< -3=) x>3/2

t/h1 x\(\le\)3/2

=) 3-2x =4x+1

=) -6x= -2

=) x= 1/3(t/m)

t/h 2 x> 3/2

=) -3 +2x= 4x+1

=) -2x= 4

=) x= -2(L)

S={ 1/3}
