3x - 3(16) = x - 2
3x - 48 = x - 2
3x - x = -2 + 48
2x = 46
x = 23
3x - 48 = x - 2
3x - x = -2 + 48
2x = 46
x = 23

3x - 48 = x+14-16
3x - x = 14-16+48
2x = 46
x = 13
3x - x = 14-16+48
2x = 46
x = 13

3(x-16)=x+14-16
3x-48=x-2
3x=-2+48
3x=46
x=15.3 (3上面有一點)(代表循環小數)

x = 23because
3x - 3(16) = x - 2
3x - 48 = x - 2
3x - x = -2 + 48
2x = 46
3x - 3(16) = x - 2
3x - 48 = x - 2
3x - x = -2 + 48
2x = 46
