1. 3x-9 = 4x+5
2. 2 (t+3) = 5 (t-1) - 7 (t-3)
3. 2 (3x+4) = 6 - (2x+5)
4. 3/4x - 2 = 1/3x + 1/2
5. (X - 3 )² = (x-2)²-5
6. 2x-4n = 3x+2n

1 Jawaban

  • 1. 3x - 4x = 9 + 5
    -x = 14
    x = -14
    2. 2t + 6 = 5t - 5 - 7t - 21
    2t - 5t + 7t = -6 - 5 - 21
    4t = -32
    t = -8
    3. 6x + 8 = -12x + 30
    6x + 12x = -8 + 30
    18x = 22
    Lainnya kerjakan sendiri ya!!!
