Solving Systems of Equations by Substitution Course
Consider the system of equations
\( x\ – \ y\ = \ 1\ –\ 2\ x\ +\ y \ = \ 6\)
Substitute \(\ x\ = \ 1\ –\ y\ \) in the second equation
\( -2(\ 1\ -\ y\ ) + y = 5 y = 2\)
Substitute\(\ y\ = \ 2\ in \ x\ = \ 1\ +\ y\)
\(\ x\ = \ 1\ + \ 2\ = \ 3\)
Example:
\( –\ 2\ x\ –\ 2\ y\ = -\ 13\)
\( –\ 4\ x\ +\ 2\ y\ = \ 10\)
\((\ 0\ .\ 5\ ,\ 6\ )\)

Whole Number Multiplication and Division Course
Multiplication:
– Learn the times tables first!
– For multiplication, line up the numbers you are multiplying.
– Start with the ones place.
– Continue with other digits
– A typical division problem:
Dividend \( \div \) Divisor\( = \) Quotient
Division:
– In division, we want to find how many times a number (divisor) is contained in another number (dividend).
– The result in a division problem is the quotient.
Example:
\(\ 200\ \times \ 90\ = \ 18,000\)
\(\ 18,000\ \div \ 90\ = \ 200\)
