Question

What are solutions of 3y>2x when y=6? Can any one help with steps plz

Answer 1

First, you just need to disregard the greater than sign because these types of equation is solved the same way as those with equals (=) sign in the middle. So when y=6,
First you need to substitute y=6 to the y in 3y

3(6)>2x

By multiplying,

18>2x

By dividing both sides of the equation by 2

18/2 > 2x/2

9>x

However if you want to transpose x to the left side of the equation, you also need to reverse the sign to <

Which means

X<9

Answer 2

If y=6 them we will have

3*6>2x
18>2x
 
x must be smaller than 9, because 
18=2*9  => 18=18, and we doesn't respect the rule

now that we know that x<9 we have other 2 cases...
1. x is a natural number x can take values from the interval [0, 8]
2. x is a rational number, so it can take values from the interval [8, - infinite)
