512. 10x−1=5x;x=15

Whether x=15 is a solution of given equation or not.
Answer to Problem 512RE
Yes, x=15 is a solution of equation 10x−1=5x.
Explanation of Solution
Given information:
A equation is given as 10x−1=5x.
Calculation:
We have been given a linear equation as 10x−1=5x. Need to verify whether x=15 is a solution of given equation. To verify this, we will put x=15 in the given equation and see if it satisfies the given equation.
Putting x=15, in 10x−1=5x
10x−1=5x10×15−1=5×152−1=11=1⇒True Statement
Hence, we can say that x=15 is a solution of given equation.
