Question

$$a\times b=b\times a$$

Solve for a

$a\in \mathrm{R}$

Solution Steps

Subtract $ba$ from both sides.

$$ab-ba=0$$

Combine $ab$ and $-ba$ to get $0$.

$$0=0$$

Compare $0$ and $0$.

$$\text{true}$$

This is true for any $a$.

$$a\in \mathrm{R}$$

Solve for b

$b\in \mathrm{R}$

Solution Steps

$$ab-ba=0$$

Combine $ab$ and $-ba$ to get $0$.

$$0=0$$

Compare $0$ and $0$.

$$\text{true}$$

This is true for any $b$.

$$b\in \mathrm{R}$$
