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.
