Answer:

x=9

Step-by-step explanation:

Since y=18

The new equation is $2x+3*6=36$

Moving some terms, it stays like the following:

$2x=36-18$

solving for x, give us that x=9

xenn [34]

Answer:

$\frac{3}{5}$

Step-by-step explanation:

Let the denominator be x
So, numerator = x - 2
According to the given condition: when 1 is subtracted from numerator and denominator both, the resulting new rational number in its simplest form is $\frac{1}{2}$

$\implies \frac{x-2-1}{x-1}=\frac{1}{2}$

$\implies \frac{x-3}{x-1}=\frac{1}{2}$

$\implies 2(x-3)=x -1$

$\implies 2x-6=x -1$

$\implies 2x-x=6-1$

$\implies x=5$

$\implies x-2=-5-2= 3$

$Required \: rational\: number = \frac{3}{5}$

I moved the real numbers to one side and and the variable to the other side to solve for the inequality

I also remembered somewhere that if you divide by a negative number the inequality sign switches.
