Question

Solve the system of in equations : x/ (2x+1) ≥ ¾ 6x / (4x-1 ) ≥ ½ . and x + 3 / ( 2x+5) ≥ -5​
please answer guys please please please

Answer 1

Answer:

First equation

x/ (2x+1) ≥ ¾ 6x / (4x-1 ) ≥ ½

Put x=1

1/3 > 3/4*6/3 > 1/2

1/3 > 2/3 > 1/2 not correct

Put x = - 1

1 > 3/4*6/5 > 1/2

1 > 18/20 > 1/2

1 > 9/10 > 1/2

So x < - 1

Second equation

x + 3 / ( 2x+5) ≥ -5

Put x = 1

4/7 > - 5

Put x=0

3/5 > - 5

Now

x+3 > - 10x - 25

11x > - 28

x > - 28/11
