Question

the average of x and y is 7, and 2= 3x+2, what is the value of y and z​

Answer 1

Answer:

hey mate here is the answer

Step-by-step explanation:

x+y= 14

x= 14-y

z= 3(14-y)+2

z= 42-3y+2

z= 44-3y

y+(44-3y)

-2y +44/2

-y+21

Answer 2

Answer:

Step-by-step explanation:

Disclaimer:

The average of $x$ and $y$ is $7$, and $2= 3x+2$, what is the value of $y$ and $x$ ?​

Concept:

The concept of average is necessary to solve this question.

Given:

The average of $x$ and $y$ is $7$ and the equation is $2= 3x+2$ .

To Find:

The value of $x$ and $y$ have to be found out.

Solution:

The average of $x$ and $y$ is $7$ .

The expression we can write as : $\frac{x+y}{2}=7$

The value of $x$ can be written as $x=14-y$

Another expression which is given is the question is that $2= 3x+2$.

Put the vale of $x$ in the above equation.

$2= 3(14-y)+2$

After further calculation we will get $3y=42$

The value of $y$ will be $y=\frac{42}{3} =14$

Put the value of $y$ in the equation $x=14-y$

The value of $x$ is $x=14-14=0$.

So the value of $x$ is $0$ and the value of $y$ is $14$ .
