Question

I need help answering these problems

Answer 1

4). x/5 =8
     x = 40
5). 2x/3 = 12
     2x = 36
      x = 36/2 = 18
6). x + 26 =12
      x = 12 - 26 = -14
7).  8x + 1 = -23
      8x = -23 -1
      8x = -24
        x = -24/8 = -3
8). 2x + 5 =15
     2x = 15 - 5
     2x = 10
       x = 10/2 = 5
9). 3x - 1 = -29
     3x = -29 + 1
     3x = -28
       x = -28/3 Or 9.33
10). 8x - 12 = 53
       8x = 53 + 12
       8x = 65
        x = 65/8 Or 8.12
11). 4x + 7 = 25
       4x = 25 - 7
       4x = 18
        x =18/4 = 9/2 Or 4.5
