x:132=123
123 x 132 =?
x + 123 = 132 * 3
x + 123 = 132 * 3
x + 123 = 396
x = 396 - 123
x = 273
x + 123 = 132 * 3
x + 123 = 396
x = 396 - 123
x = 273
x + 123 = 132 x 3
x + 123 = 396
x = 396 - 123
x = 273

So sánh x và y biết:
a) x = 3,21(132); y= 3,21(123)
b) x = 0,212112...; y = 0,2121112...
c) x = -2,257917; y = -2,257913...
Y - 132 =123 *132
tìm Y * 159
Tìm số nguyên x, biết: a) (215 + x) - 215 = 0; b) ( -444) - ( x - 444) = 0 c) 123 - (132 - x) = 0; d) 85 - ( 85 + x) = 0
