29. Consider the equation:

3(1 + px) = 12x
For what value of p does the equation have no solution?

D. 36

Answer 1

I think it’s C.

Explanation: sorry if I’m wrong..

Answer 2

The answer is actually B.

Explanation:

3(1+4x)=12x

(3)(1)+(3)(4x)=12x(Distribute)

3+12x=12x

12x+3=12x

Step 2: Subtract 12x from both sides.

12x+3−12x=12x−12x

3=0

Step 3: Subtract 3 from both sides.

3−3=0−3

0=−3

(Can't be negative)
