Question

6- y = 9 please solve this equation
​

Answer 1

Answer:

$\large\boxed{y=-3}$

Step-by-step explanation:

To solve this problem, first you have to isolate by the y on one side of the equation. Remember to solve this problem, addition property of equality is adding from both sides of an equation by the same number doesn't change the equation.

Given:

6-y=9

Solution:

First, subtract 6 from both sides.

$\displaystyle 6-y-6=9-6$

Solve.

$\displaystyle 9-6=3$

$\displaystyle -y=3$

Secondly, divide by -1 from both sides.

$\displaystyle\frac{-y}{-1}=\frac{3}{-1}$

Solve.

$\displaystyle 3\div-1=\boxed{-3}$

$\large\boxed{y=-3}$

Therefore, the correct answer is y=-3.

Answer 2

Answer:

=> y = -3

Step-by-step explanation:

Given that:-

$6- y = 9$

To find:- The value of the expression,

In order to solve that, we have to use the concept of BODMAS:

It is the sequence of various mathematical operations which is used to solve the various expressions.

As we have,

=> $6- y = 9$

Rearrange the terms,

=> $-y+6=9$

Subtract $6$ on both sides,

=> $-y+6-6=9-6$

Simplifying it further, we get

=> $-y = 3$

=> $y = -3$

Hence, the required solution is -3.
