Answer 2

Answer:

=> y = -1

Step-by-step explanation:

Given that:-

$15y = 10y - 5$

To find:- The value of the expression:

Here we will use the transposition method.

We have to follow these steps:-

( i ) First of all, we have to identify the variables and the constants.

( ii ) Get the variable to one side of the equation. Maintain equation balance while calculating.

( iii ) Then solve the expression of both sides by using various mathematical operations. Simplify both sides.

As we have,

=> $15y = 10y - 5$

We move all terms to the left:

=> $15y-(10y-5)=0$

Simplifying it further,

=> $15y-10y+5=0$

Then add all the numbers, as well as the variables

=> $5y+5=0$

Now, subtract both sides by $5$

=> $5y=-5$  

Divide both sides by $5$, we get

$=> y=-1$

Hence, the required solution is -1.
