Solve: 3[-x+(2x=1)]=x-1 I can't distribute so I don't know what to do.

Below

Step-by-step explanation:

● 3 ( -x +2x - 1) = x - 1

● 3 ( -x -1 ) = x - 1

● -3x -3 = x - 1

Add -x to both sides

● -3x -3 - x = x -1 -x

● -4x -3 = -1

Add 3 to both sides

● -4x - 3 + 3 = -1 + 3

● -4x = 2

Divide both sides by -4

● -4x/-4 = 2/-4

● x = -1/2

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.
