Question

i need an answer please

Answer 1

after takinf lcm
(10x+7)/2 = (3x-28)/2
10x+7 = 3x-28
10x-3x = -28-7
7x = -35
x= -5

Answer 2

⇒ 5x + ( 7/2 ) = ( 3/2)x - 14

⇒ 5x + 3.5 = 1.5x - 14    { 7/2 = 3.5 and 3/2 = 1.5 }

⇒ 5x - 1.5x = - 14 - 3.5

⇒ 3.5x = -17.5

⇒ x = ( -17.5 ) ÷ 3.5

⇒ x = -5.

Verification :

L.H.S = 5x + 3.5

          ⇒ 5 ( -5 ) + 3.5

          ⇒ -25 + 3.5

          ⇒ -21.5

R.H.S = 1.5x - 14

         ⇒ ( 1.5 ) ( -5 ) - 14

         ⇒ -7.5 - 14

         ⇒ -21.5

∴L.H.S = R.H.S verified .


Hence , x = -5.
