Simplify the expression 52yx / 5x - x and find the value of p from 24 = 6 + 2p.

Here are the solutions to the problems:

6.

a) Simplify the expression $52yx \div 5x - x$

Step 1: Perform the division first according to the order of operations.

$$\frac{52yx}{5x} = \frac{52y}{5}$$

Step 2: Substitute the simplified division back into the expression.

$$\frac{52y}{5} - x$$

The simplified expression is $\boxed{\frac{52y}{5} - x}$.

b) Find the value of $p$ from $24 = 6 + 2p$

Step 1: Subtract 6 from both sides of the equation.
