Solving Systems of Equations

Front

What is the best method to use for solving the system of equations?
y = 6x − 11
−2x − 3y = −7
Options: Graphing, Substitution because a variable is defined, Elimination because both equations are in standard form.

Back

Substitution because a variable is defined

Front

What is the best method to use for solving the system of equations?

2x − 3y = −1

y = x − 1

Back

Substitution because a variable is defined

Front

What is the best method to use for solving the system of equations:

−4x − 2y = −12

4x + 8y = −24

?

Back

Elimination because the equations are in standard form.

Front

Set up the equation to begin solving: y = 6x − 11 and −2x − 3y = −7

Back

-2x - 3(6x-11)= -7

Front

What variable do you eliminate in the system of equations:
4x + 8y = 20
−4x + 2y = −30?

Back

X because they have opposite signs

Front

What is the proper set up to solve the equation?
-7x -2y= -13
x = 2y+11
Options:
-7(11) -2y = -13
-7(2y +11)-2y = -13
-7x -2(11) =-13
-7x - 2(2y+11)= -13

Back

-7(2y +11)-2y = -13
