Lesson 33: SOLVING LINEAR SYSTEM OF EQUATIONS
ALGEBRAICALLY BY ELIMINATION METHOD
OF ADDITION:
DAY 2
Date: _________
Elimination Method: Remember you need opposite terms to eliminate by adding
the two equations together. You may have to multiply the entire equation(s) by a
number to create the opposite terms.
Solve each system by elimination. Include a check where indicated.
1.)
4x – 3y = 6
5x – y = –20
2.)
Solution is: ___________
CHECK: (Both Equations)
3x – 2y = 2
10x – 10y = 20
Solution is: ___________
3.) How many solutions to the following system of equations?
10x + 40y = 12
A) One Solution
–5x – 20y = –15
B) No Solution
C) Infinitely Many Solutions
4.)
–2x + y = 1
y = 3x – 4
Get equation in Ax + By = C form
Solution is: ___________
CHECK:
