Part 3: Evaluating Variable Expressions
Evaluate means to find the value of, or simplify. Substitute the given values and solve.
1.)
15 - x + y, if x = 9 and y = 11
2.) (6c + 2b) - 11, if a = 8, b = 5, and c = 3.

14. (05.02 lc) what is the value of y in the solution to the following system of equations? (5 points) 2x + y = −4 5x + 3y = −6

Axel follows these steps to divide 40 by 9: start with 40. 1. divide by 9 and write down the remainder. 2. write a zero after the remainder. 3. repeat steps 1 and 2 until you have a remainder of zero. examine his work, and then complete the statements below.
