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
