What is the answer to this math problem 4y+1=9

Y=2

Step-by-step explanation:

Simplifying

4y + 1 = 9

Reorder the terms:

1 + 4y = 9

Solving

1 + 4y = 9

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-1' to each side of the equation.

1 + -1 + 4y = 9 + -1

Combine like terms: 1 + -1 = 0

0 + 4y = 9 + -1

4y = 9 + -1

Combine like terms: 9 + -1 = 8

4y = 8

Divide each side by '4'.

y = 2

Y=2

Subtract the 1 from both sides and you have 4y=8. Then you divide both sides by 4 and you get y=2

Step-by-step explanation:

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.
