Alice solved the following equation: -18 - 3 x = 12 -3 x = 6 x =-2 which of the following statements is true? alice is correct. the 6 should be 30 in step two. the 6 should be -6 in step two. the 6 should be -4 in step two.

The 6 should be 30 in step two.

EXPLANATION

Following the Addition Property of Equality, you have to transpose the constant term to the other side by adding its negative or opposite value on both sides.

That is,

-18 - 3 x = 12
-18+18 - 3 x = 12+18
-3x=30

Following the equation, you'll have

-3x=30
x=-10
