You will need to solve it like an equation, by keep the inequality sign.
The less than or equal to sign can be written as "& l e ;" without the quotes and the intevening spaces.
- Group like terms on same side of inequality sign
- reduce to one term on each side
- divide each side by the coefficient of the unknown, flip the direction of inequality if the coefficient is negative.
