Question

solve x/4 + x/3 + 2x/5 +3 = x and then find y if 1/x + 1/y = 2

answer = value of x is 180 and y is 180/359

Answer 1

Answer:

3(2x−5)−7}≥9(x−5)

{6x−15−7}≥(9x−45)

{−22}≥(3x−45)

{45−22}≥3x

3x≤23

x≤

3

23

x≤7.666

Answer 2

Answer: x=180 and y=180/359

Step-by-step explanation:

First we take the LCM

=15x+20x+24x+180/60=x

=59x+180/60=x

We can write x as x/1

=59x+180/60=x/1

Now we do cross multiplication

=1(59x+180)=x(60)

=59x+180=60x

=59x - 60x = -180

-x= -180

x=180

Now, 1/x + 1/y = 2

1/180 + 1/y = 2

1/y=2 - 1/180

1/y= 360 - 1/180

1/y = 359/180

So 1/y = 359/180 to find the value of y we will do the reciprocal

So,y = 180/359
