Question

if -15 + x = 30, then x is​

Answer 1

Answer:

By transposition method,

-15 + x = 30

x = 30 + 15 = 45

Answer 2

Answer:

Hence we get the value of x$=45$

Step-by-step explanation:

As per the data in given equation

In above question it is given that

We have find the value of given expression

Given the data in question -15 + x = 30,

We have find the value of x

Hence, for solving the above equation, we will solve it by separating the like terms at one side.

So, we will shift15 from LHS to RHS the sign will change from negative to positive,

As we get,

$-15x+x=30\\x=30+15\\x=45$
