1. If 9 times a number is added to 18, the result is -27. Find the number.

Let j be the number.
9j, " 9 times a number"
9j%2B18, "is added to 18" ----- do not misunderstand the "is" in the phrase.
expression=-27, "result is -27", Now the equation is described;

Equation to solve is highlight%289j%2B18=-27%29


2. ...measure whose complement is...
Complement means the angle plus the other angle equals 90 degrees.
Let m be the measure of "an angle".
90-m is the complement of m.
highlight%2890-m=8%2Am%29; solve for m.
