8x + 4 = 3 (X - 1) + 7

0

Step-by-step explanation:

8x + 4 = 3x - 3 +7

u first expand the bracket as I have done above

then u evaluate those who have like terms close like -3 + 7

8x + 4 = 3x + 4

then u group like terms ie. the values with the variable x on one side of the equation and the ones without x on the other side of the equation

8x - 3x = 4 - 4

8x - 3x = 0

5x = 0

then u divide both side by the coefficient of x

0/5 but any number divided by 0 is 0, so x = 0

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
