Step-by-step explanation:
1) 3x/ 2 + 1 = 11 / 2
3x / 2 = 11/2 - 1
3x /2 = 9 /2
6x = 18
x = 3 answer
íí ) 3 +x/3 = x/2
3 = x/2 - x /3
3 = (3x - 2x )/6
3 = x/6
x = 18 answer
ííí) 3x =15 - 2x
3x +2x = 15
x = 3 answer
ív) x/4 = 3 +x /5
or, x /4 = (15 + x)/ 5
or, 4 ( 15 + x ) = 5x
or, 60 + 4x = 5x
or, x = 60 answer
