Answer:

x = -1

Step-by-step explanation:

-2(x - 5) = 12

-2x + 10 = 12 (this is the mistake, -2 times -5 = + 10)

-2x = 12 - 10

-2x = 2

x = 2/(-2)

x = -1

Answer:

-2(x - 5) = 12

-2x + 10 = 12

-2x + 10 - 10 = 12 - 10

-2x = 2

-2x/-2 = 2/(-2)

x = -1

Thus, The answer is (-1) and the mistake is multiplication of sign i.e.,

[ (-) × (-) = (-) ] this is wrong ×

But

[ (-) × (-) = (+) ] this is right ✓
