Question

Tolong nomor 1-10.pertanyaan ini khusus kak syubbana

Answer 1

1) B
2) 3x - 5 = 16
    3x = 21
     x = 7

3) -3x - 5 = -5x + 11
     -3x + 5x = 11 + 5
     2x = 16
     x = 8

4) 2x + 7 + 24 = 51
    2x = 51 - 31
    2x = 20
    x = 10

5) A

6) 10x - 12 = 18
     10x = 18+12
      10x = 30

7) x + x+1 = 33
     2x + 1 = 33

8) 3x + 10 = 5x - 4
    3x - 5x = -4 - 10
     -2x = -14
     x = 7

9) 6x - 3 = 2x - 11
    6x - 2x = -11 + 3
     4x = -8
      x = -2

10) 3(x-5) = 7x + 1
     3x - 15 = 7x + 1
     3x - 7x = 1 + 15
      -4x = 16
       x = -4
