#### $$\dfrac{2\frac35-1\frac23}{\frac23-\frac35}$$

##### Re: $$\dfrac{2\frac35-1\frac23}{\frac23-\frac35}$$

$$\frac{2\frac{3}{5}-1\frac{2}{3}}{\frac{2}{3}-\frac{3}{5}}=\frac{\frac{13}{5}-\frac{5}{3}}{\frac{2}{3}-\frac{3}{5}}$$
$$=\frac{\frac{39-25}{15}}{\frac{10-9}{15}}$$
$$=\frac{\frac{14}{15}}{\frac{1}{15}}$$
$$=\frac{14}{15}\cdot\frac{15}{1}=14$$

#### If 2x - 3y = 6, then 6y - 4x =

##### Re: If 2x - 3y = 6, then 6y - 4x =

Given to that 2x - 3y = 6
What is the value of 6y - 4x?
From 2x - 3y = 6 --- eqn (1)
Multiplying both sides of Eqn. 1 by 2, we have
4x - 6y = 12
-12 = 6y - 4x
6y - 4x = -12
From the above, the value of 6y - 4x = -12. Hence, the correct answer is option A.

##### Re: If $$a?b = 3a^2 + 2b - 1,$$ then $$2?3 =$$

$$2?3=3\left(2^2\right)+2\left(3\right)-1$$
$$=3\left(4\right)+6-1$$
$$=12+6-1=17$$
