HELP I NEED HELP ASAP PLEASEEEEE!!!!!!


Solve each given equation and show your work. Tell whether each equation has one solution, an infinite number of solutions, or no solution. Explain your answers.


1) 2x + 4(x-1) = 2 + 4x

2) 25 - x = 15 - (3x + 10)

3) 4x = 2x + 2x + 5(x-x)

Respuesta :

Answer:

1) 2x+4(x-1)= 2+4x = x = 3

2) 25 - x = 15 - (3x + 10) = x = -10

3) 4x = 2x + 2x + 5(x-x) = x = any value of x make the equation true

Step-by-step explanation:

1) 2x+4x-4=2+4x

6x-4=2+4x

6x-4+4=2+4x+4

6x=4x+6

6x-4x=4x+6-4x

2x=6

2x/2 = 6/2

x= 3

2) 25-x=-3x+5

25-x-25=-3x+5-25

-x=-3x-20

-x+3x=-3x-20+3x

2x=-20

2x/2 = -20/2

x= -10
