Question

19. How many solutions does the equation -2(x + 4) = 2(x + 4) - 6 have?​

Answer 1

Answer:

one(1)

Step-by-step explanation:

-2(x + 4) = 2(x + 4) -6

open the brackets

-2x - 8 = ( 2x + 8)-6

-2x - 8 = -12x - 48

collect like terms (c. l. t)

-2x + 12x = -48 +8

10x = -40

divide both side by 10

10x/10 = -40/10

x=-4
