Question

HELP PLEASE !!!!!what is the answer to 3 over 4 x - 9 = 27 please help

Answer 1

Would that look like $\frac{3}{4x-9} = 27$? If so, you can multiply both sides by (4x-9) to cancel the 4x-9 on the bottom and get it onto the other side. It would look like this: $\frac{4x-9}{1} \times \frac{3}{4x-9}= 27 \times \frac{4x-9}{1} \\ 3 = 27(4x-9)$.

Distribute the 27 to the 4x and -9, which will get you this:$3=108x-243$.

Then you want to add the 243 on both sides to isolate the x which should get you this: $246=108x$.

Your next to final step is to divide both sides by 108 to leave the x alone. This will appear like this: $x= \frac{246}{108}$.

Your last step is to simplify the fraction or convert it into a decimal depending on which you prefer. If simplified, you should get $x=13\frac{2}{3}$ and for a decimal you will get $x=13.67$
