solve this please fast....
1) 6(3x+1)-3(4x-2)=2(x-5)-3(2x-2)
2) 3(x-2)-2(x-3)=4(x-5)+5(x-8)
3) 7(2t-3)+2(3t+2)=t+5
4) 12-2/3(2x-5)+3x=5

Hey Anuj,

Here is your solution :

1. 6 ( 3x + 1 ) - 3 ( 4x - 2 ) = 2 ( x - 5 ) - 3 ( 2x - 2 )

⇒ 18x + 6 - 12x + 6 = 2x - 10 - 6x + 6

⇒ 18x - 12x + 6 + 6 = 2x - 6x -10 + 6

⇒ 6x + 12 = -4x - 4

⇒ 6x + 4x = -4 - 12

⇒ 10x = -16

⇒ x= -16 ÷ 10

∴ x = -1.6 = -8/5

2. 3 ( x - 2 ) - 2 ( x - 3 ) = 4 ( x - 5 ) + 5 ( x - 8 )

⇒ 3x - 6 - 2x + 6 = 4x - 20 + 5x - 40

⇒ 3x - 2x - 6 + 6 = 4x + 5x -40 - 20

⇒ x = 9x - 60

⇒ x - 9x = - 60

⇒ -8x = -60

⇒ x = -60 ÷ ( - 8 )

∴  x = 7.5 = 15/2.


3. 7 ( 2t - 3 ) + 2 ( 3t + 2 ) = t + 5

⇒ 14t - 21 + 6t + 4 = t + 5

⇒ 14t + 6t + 4 - 21 = t + 5

⇒ 20t - 17 = t + 5

⇒ 20t - t = 5 + 17

⇒ 19t = 24

∴  t = 24/19.

4. 12 - ( 2/3 ) ( 2x - 5 ) + 3x = 5

⇒ 12 - ( 4x/3 ) + ( 10/3 ) + 3x = 5

        36 - 4x + 10 + 9x
⇒  ---------------------------------------  = 5
                       3

              46 + 5x
⇒ ----------------------------  = 5
                  3

⇒ 46 + 5x = 5 × 3

⇒ 46 + 5x = 15

⇒ 5x = 15 - 46

⇒ 5x = -31

∴  x = -31/5 = - 6.2


Hope it helps !!
