Question 4
What is the solution to 2(x−4)=16?

x = 12

Step-by-step explanation:

2(x-4)=16

2 times x +2 times -4 = 16

2x -8 =16

2x -8 (+8) =16 (+8)

2x = 24

2x (divided by 2) = 24 (divided by 2)

x = 12

the correct answer is the second option

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
