Can some pls help me . Thank You !

x = -4

Step-by-step explanation:

First we multiply 3 by 4x and 1. We will get 12x and 3. The equation should then look like this: -79 = 7x + 12x -3.

Second, consolidate. 7x + 12x = 19x. Your equation should then look like this -79 = 19x - 3.

Third, add 3 to both sides. Your equation should then look like this. -76 = 19x.

Lastly, divide both sides by 19. You should get an answer of -4 = x.

Step-by-step explanation:

3x+2(5x-3)=7

the answer to that is: x = 1

-79= 7x+3(4x-1)

the answer to that is: x = - 4

9-4(2x-1)= 45

the answer to that is: x= -4

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
