How many solutions are there to the equation below 11x - 99 = 11 (x- 9)

all values of x are solutions

Step-by-step explanation:

There are infinite number of solutions for 11x - 99 = 11(x - 9)

Solution:

Given, equation is 11x – 99 = 11 ( x – 9 )

We have to find the number of solutions that the given equation has.

Now, let us simplify the given equation

11x – 99 = 11 (x – 9 )

11x – 99 = 11x – 99

11x – 11x = 99 – 99

0 = 0  

L.H.S = R.H.S

Here, we didn’t get a particular solution, so any value of x can satisfy the given equation

Hence, the given equation has infinite number of solutions.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
