3(12x – 9) + 9 = 2x + 4 Would this be infinite solution, one solution or no solution?

timama [110]

Answer:

One solution

Step-by-step explanation:

Let us first expand the left side of the equation to rid of the parenthesis:

$3*12x-3*9+9=2x+4\\36x-27+9=2x+4\\36x-18=2x+4$

Now let us isolate the variable to sove for x:

$36x-2x=4+18\\34x=22\\x=\frac{22}{34}\\x=\frac{11}{17}$

Therefore, x= $\frac{11}{17}$ . As you can see, there is just one solution.

I hope this helps! Please let me know if you have any further questions :)
