How many solutions does the following equation have?

RoseWind [281]

Answer:

There will be No solution for the equation $9x - 4 = - 3x + 5 + 12x$ . Option B is correct.

Step-by-step explanation:

We need to determine how many solutions the equation $9x - 4 = - 3x + 5 + 12x$ have.

Solving the equation and finding the solutions

$9x - 4 = - 3x + 5 + 12x$

Combining like terms, Moving 3x and 12x to left side of equality and changing their signs and moving 4 on right side of equation and changing sign.

$9x +3x-12x = 5 + 4$

Simplifying

$12x-12x = 9\\0=9$

Solving the equation we get 0=9 which is false. So, there will be No solution for the equation $9x - 4 = - 3x + 5 + 12x$ . Option B is correct.
