The variables already have coefficients.......

\(\dfrac{2x-1}{3}=4x\\ 2x - 1 = 12x\\ 10x = -1\\ x = -\dfrac{1}{10}\)

Now we seldom tell jokes here......

Normal users always says 'Math question please' unless it is a math joke question.

Now only a little part of normal users like GingerAle and Nauseated(not seen recently) and the 2 mods: Melody and CPhill may tell math jokes.......

BTW I am kinda new. I registered on April 2016.

You know what is SOHCAHTOA?

Sine of an angle is Opposite over Hypotenuse. : SOH

Cosine of an angle is Adjacent over Hypotenuse. : CAH

Tangent of an angle is Opposite over Adjacent. : TOA

Hope this helps :)

PS: This is cookie-coloured :)

\(\color{BurntOrange}{\dfrac{3}{8} \times \dfrac{5}{9}\\ =\dfrac{\not3^1}{8}\times \dfrac{5}{\not9_3}\\ =\dfrac{5}{8\times 3}\\ =\dfrac{5}{24}}\)

It was EP. I don't know what is geometrical means.

The 2 figures are congruent.

Rotation and reflection does not affect the size of the figures.

\(E^2 - 1 = 3\\ E^2 =4\\ E = \pm 2\)

(8t - 32)(t + 1)

= 8t² - 32t + 8t - 32

= 8t² - 24t - 32
