Answer 1

Respuesta:

Explicación paso a paso:

2) 10 + 4(X - 4) = 20

   10 + 4X -16 = 20

   4X = 20 -10 +16

   4X = 26

     X = 26 / 4

     X = 13/2

3) 3X + 7 + X = 25

   4X = 25 - 7

   4X = 18

     X = 18 / 4

    X = 9/2

4) 2(X + 1) + 12 = 75

   2X + 2 +12 = 75

   2X = 75 -2 - 12

   2X = 61

     X = 61/2

5) 3(X + 3) + 2X = 45

   3X + 9 + 2X = 45

   5X = 45 - 9

   5X = 36

    X = 36/5
