Question

Solve and verify the answer
2. 2x - (1 - 2x) = 5 - 3(1 + x)​

Answer 1

Answer:

given,

2x-(1-2x) = 5-3(1+x),

=> 2x -1+2x = 5-3-3x,

=> 4x+3x = 2+1,

=> 7x = 3,

=> x = 3/7.

verification :

2(3/7) -(1-2(3/7)) = 5-3(1+3/7),

=> (6/7) -1 +(6/7) = 5-3-(9/7),

=> (12-7)/7 = (14-9)/7,

=> 5/7 = 5/7.

Hence ,proved.
