III. άhe tundmatuga lineaarvυrrand
1. Lahenda jδrgmised vυrrandid:
| a) 6(x - 4) + 12(3 - 2x) = 0
.
..
|
f) 7(z - 2) - 2(2z + 3) = - 10
.
|
| b) - 2(3y + 4) + 3(3y + 5) = 2
. . . |
g) 25(4x - 5) - 20(9 - 2x) = -25
|
| c) 15(2x - 8) - 9(2 - 5x) = 12
|
h) 17(3x + 2) - 6(9 + 8x) = 13
.
|
| d) 23(4x + 2) - 7(12x - 2) - 60 = 0
. . . |
i) 21(x - 3) + 4(3x + 1) = - 59
..
|
| e) 8(9x - 2) + 2(14x + 8) = 100
. . . |
j) 19(3x - 2) + 4(11x + 14) = 99x
