Solve by Substitution
Solve the systems of equations using substitution:
-3x + 4y = -2
y = -5
(-6, -5)
Solve the systems of equations using Elimination:
14x + 2y = 26
-14x - 6y = -50
(1, 6)
What strategy would you use?
14x + 2y = 26
-14x - 6y = -50
elimination because the coefficients of x will cancel out.
Where is Mr. Sutz from?
New York aka
Solve the systems of equations using substitution:
-5x - 5y = 10
y = -4x -17
(-5, 3)
Solve the systems of equations using Elimination:
-3x - 5y = 2
3x + 5y = 7
No Solution
What strategy would you use?
-5x - 5y = 10
y = -4x -17
substitution because y is already solved for.
Does Mr. Sutz have a girlfriend?
Yes
Solve the systems of equations using substitution:
y = -2x - 9
3x -6y = 9
(-3, -3)
Solve the systems of equations using Elimination:
-6x - 10y = 4
6x + 10y = -4
Infinitely Many
Is there 1 solution, No solution, or Infinite solutions for the system of linear equations below? AND JUSTIFY WHY
3x - y = 19
-3x + y = 10
No Solutions because it is a false statement.
Does Mr. Sutz drink Coffee?
Yes
Solve the systems of equations using substitution:
-8x - 5y = -24
-x + y = 10
(-2, 8)
Solve the systems of equations using Elimination:
x + 8y = 2
3x + 4y = 26
(10,-1)
Mathematically, what will our answer look like if we determine there is no solution?
4 = 2 (Any two numbers that are not equal to each other with no variables)
Does Mr. Sutz go white water rafting?
Yes
Solve the systems of equations using substitution:
-8x + y = -7
16x - 2y = 14
Infinitely Many Solutions
Solve the systems of equations using Elimination:
-5x + 7y = -7
-2x - 2y = 2
(0, -1)
What is the first step in solving this system of equations by elimination?
3x +2y = 10
x + 7y = -15
Multiply the bottom equation by -3
Does Mr. Sutz have any math tatoos?
No
