Step-by-step explanation:

x + 2(x-1) = 5/2

=> x + 2x - 2 = 5/2

=> 3x - 2 = 5/2

=> 3x = 5/2 + 2

=> 3x = (5+4)/2

=> 3x = 9/2

=> x = 9/2÷3

=> x = 9/2×1/3

=> x = 3/2

VERIFY—:

=> x + 2(x - 1) = 5/2

=> 3/2 + 2( 3/2 - 1) = 5/2

=> 3/2 + 2 {( 3-2/2 ) } = 5/2

=> 3/2 + 2 × 1/2 = 5/2

=> 3/2 + 1 = 5/2

=> ( 3+2)/2 = 5/2

=> 5/2 = 5/2

I hope this answer is helpful for you.......✌️✌️
