Question

3(2x + 1) - 4(x - 2) = 0​

Answer 1

Answer:

ANSWER

3(2x−1)

2

+4(2x−1)−4=0

say t=2x−1, then

⇒3t

2

+4t−4=0

⇒3t

2

+6t−2t−4=0

⇒3t(t+2)−2(t+2)=0

⇒(3t−2)(t+2)=0

∴ t=

3

2

or t=−2

⇒2x−1=

3

2

or 2x−1=−2

⇒x=

6

5

or 2x=−1

∴ x=1/2 or 5/6 or x=−1/2

Answer 2

Answer:

6x +1 - 4x+8 = 0

2x+11=0

2x=0-11

2x= -11

x= -11/2
