Question

if 2(x+1)/3 - 2(x-1)/4 = 1, find x

​

Answer 1

Answer:

2

x+1

=4

x−3

2

x+1

=2

2x−6

By Comparing powers

x+1=2x−6

⇒x=7

Answer 2

Answer:

x = 7.5

Given that ;

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

By Cross Multiplication ;

3 × 2 ( x - 1 ) - 4 × 2 ( x + 1 ) = 1

6x - 6 - 8x - 8 = 1

- 2x - 14 = 1

- 2x = 1 + 14

x = - 15 / 2

x = - 7.5
