Question

To solve the equation, Antwan uses the distributive property, combines like terms, then uses the addition and subtraction properties of equality to isolate the variable term on one side of the equation and the constant term on the other side. What are the possible values of the constant after Antwan has completed these steps?

3(1/3x+1)+4=-1-4(x+3)

Answer 1

D. -20 or 20

Explanation:

Answer 2

3(1/3x + 1) + 4 = -1 - 4(x + 3)
x + 3 + 4 = -1 - 4x - 12
x + 7 = -13 - 4x

**x + 4x = -13 - 7
5x = - 20........<== one possible value is - 20

**7 + 13 = -4x - x
20 = -5x <=== another possible value is 20
