III. άhe tundmatuga lineaarvυrrand
1. Lahenda jδrgmised vυrrandid:
| a) 24 + 2x - 3 = x + 5 - 3x
|
f) 53 - 9x - 7 = 2x - 18 - 3x
.
.
|
| b) 3x + 24 - 12x = 37 - 13x + 55
.. . . . |
g) y + 13 - 2y = 2 + 5y - 37
.
.
|
| c) 6x + 21 - 2x = 10 - 2x - 13
. . . |
h) 24 + 3x - 11 = 8x + 29 - x
.
..
|
| d) 4x + 15 - x = 9 - 5x - 42
. . . |
i) 5x - 39 + 17x = 8 + 18x + 17
|
| e) 42 - 7x - 22 = 5x + 92 - 8x
. . . |
j) 5x + 3 - x = 47 + 8x - 8
