Question

5) x +6 = -11
6) 2x -6 = -14

Answer 1

5.  x + 6 = -11
            x = -11-6 = -17

6.  2x - 6 = -14
          2x = -14+ 6
          2x = - 8
            x = - 8/2
            x = - 4

Answer 2

Maka cari nilai x nya

5) x + 6 = -11
    x + 6 +(- 6) = -11 +(- 6)
    x = -17
6) 2x - 6 = -14
    2x - 6 + 6 = -14 +6
   2x = -8
    x = 1/2 x -8 = -4
