doy corazon y corona al que me haga esto​

Answer 1

1) 1/3x - (-3/4) - R25/4 = 3/1

1/3x + 3/4 - 5/2 = 3/1

1/3x - 7/4 = 3/1

x/3 = 12/4 + 7/4

x = 57/4

2) 3/2x - 9/4 = 7/2 : 1/3

18x/12 - 27/12 = 42/12 : 4/12

18x - 27 = 42/4

72x - 108  = 42

72x = 150

x = 2,08

3) -1/2x + 4/3 : -1/2 = 1/9 · 2/1

-1/2x + 8/-3 = 2/9
