Question

resolver y probar cada ecuación
5 - 3x/4 = 1/9

5x/16 + 9/4 = 3/5

2x + 4 = 6

Answer 1

5 - 3x/4 = 1/9
5 - 1/9 = 3x/4
44/9 = 3x/4
44/9 / 3/4 = x
176/27 = x
6.52 = x


5x /16 + 9/4 = 3/5
5x/16 = 3/5 - 9/4
5x/16 =  - 33/20
       x =  - 33/20 / 5/16
       x =  - 132/25
       x =  - 5.28 

2x + 4 = 6
      2x = 6 - 4
      2x = 2
        x = 2/2
        x = 1
