Answer:
B.
Explanation:
x + 3x + 6 = 6 + 4x
4x + 6 = 6 + 4x
- Transfer like terms to the same side of the equation.
4x - 4x = 6 - 6
- When we add and subtract like expressions, the result will be 0 = 0.
This means, whatever value we pick in place of x, there will always be a solution therefore, the equation in option B has infinitely many solutions.
