1) 360 + x = 1320x = 1320 - 360x = 960
2) x/3 + 140 = 212x/3 = 72x = 72 * 3x = 216
3) x + 100 = 360x = 360 - 100x = 260
Итак, решения уравнений:1) x = 9602) x = 2163) x = 260.
1) 360 + x = 1320
x = 1320 - 360
x = 960
2) x/3 + 140 = 212
x/3 = 72
x = 72 * 3
x = 216
3) x + 100 = 360
x = 360 - 100
x = 260
Итак, решения уравнений:
1) x = 960
2) x = 216
3) x = 260.
