Which value of x is different from the others?

a) 5x + 4 = - 6

b) x/2 + 3 = 2

c) 2 (x + 7) = 10

d) - 2 = - x

d

Step-by-step explanation:

5x + 4 = - 6

5x = - 6-4

5x=-10

x=-2

The value of the first expression is x=-2.

x/2 + 3 = 2

x/2 = 2-3

x/2 = - 1

x=-2

The value of the second expression is x=-2.

2x+14=10

2x=-4

x=-2

The value of the third expression is x=-2.

-2=-x

2=x

The value of the fourth expression is x=2.
