III. άhe tundmatuga lineaarvυrrand
1. Lahenda jδrgmised vυrrandid:
| a) 5 - 4x + 9 = 2x - 10
.
.
|
e) 24x = 17 + 9x + 42 + 1
|
| b) 5 - 8y = - 23 + y + 1
.. . .. |
f) 87x - 43 - 19x = 48x + 37
.
|
| c) 9 - 4x - 47 = 3x - 3
.
. .. .. |
g) 11 - 17y = 18y - 76 - 18
.
|
| d) 38 - 27x = 21 + 3x - 43
.. .. .. |
h) 7 - 49 = y + 3 - 6y
.
|
2. Lahenda jδrgmised vυrrandid:
| a) 7 + y + 1 = 2y - 4 + 3y
.
|
c) 21x - 15 + 2x = 19 + 9x + 36
..
|
| b) - 4x + 7 + 11x = 23 - 6x + 49
. . . |
d) 54 + 13x - 24 = 7x + 30 - 9x
