Pleas help with this. Explain the steps so I can understand what I am doing.
solve
0.3x + 9<_ 0.7x 8
the solution is {xx ? ? }
_ this line is suppose to go under the 9 but I don't know how on computer do you?

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.
