Solve -x/7-2/3=4/21 please help thank you

x = -6

Step-by-step explanation:

Step 1:

Simplify

-1/7x + -2/3 = 4/21

Step 2:

Add 2/3 to both sides

-1/7x + -2/3 + 2/3 = 4/21 + 2/3

-1/7x = 6/7

Step 3:

Multiply both sides by 7/-1

7/-1 x -1/7x = 7/-1 x 6/7

x = -6

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.
