Question

What is the solution to the equation -2(2x + 4) + 10 = 8x + 14?

A.
x = 3.5

B.
x = -1

C.
x = 1

D.
x = -3.5

Answer 1

$-2(2x+4)+10=8x+14\\\\-4x-8+10=8x+14\\\\-4x-8x=14+8-10\\\\-12x=12 \ \ /:(-12)\\\\\huge\boxed{x=-1}$

Answer 2

Answer:

-1

Step-by-step explanation:

-2(2x + 4) + 10 = 8x + 14

-4x - 8 + 10 = 8x + 14

-4x + 2 = 8x + 14

-4x - 8x = 14 - 2

-12x = 12

x = -12/12

x = -1
