Variables y and x have a proportional relationship, where y = 18 when x = 2.

Tanya [424]

Answer:

x = 4

Step-by-step explanation:

If y = 36, that means the original y = 18 was multiplied by 2. So, we have to multiply x = 2 by 2 as well.

2 * 2 = 4, so x = 4

What is the value of x?<br> 3/5x – 1/3 x = x – 1

Aleks04 [339]

The first step to solving this is to multiply both sides of the equation by 15.
9x - 5x = 15x - 15
Collect all of the like terms on the left side of the equals sign.
4x = 15x - 15
Move the variable to the left side of the equation and change its sign.
4x - 15x = -15
Now collect the like terms on the left side of the equation for the second time.
-11x = -15
Lastly,, divide both sides of the equation by -11 to get your final answer.
$\frac{15}{11}$
This means that the correct answer to your question is $\frac{15}{11}$ ,, or 1 $\frac{4}{11}$ simplified.
