Is x = -3 a solution for the following equation: 6x - 19 = 3x - 10? Be sure to show work.

-1

Step-by-step explanation:

if x is the solution, substitute the value of x in that equation

x -3 = 0

so substitute 3 as x

6(3) - 19 = 3(3) - 10

18 -19 = 9 - 10

-1 = -1

No it is x = 3

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

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.
