Here is a review over different substitution concepts.
2
Multiple Choice
Given the following equation, which variable should you use for substitution and in which equation?
5x + 3y=10 x=2y −3X in the FIRST equation
Y in the FIRST equation
X in the SECOND equation
Y in the SECOND equation
3
Multiple Choice
Given the following equation, which variable should you use for substitution and in which equation?
y=−3x−11 4x + 2y =1X in the FIRST equation
Y in the FIRST equation
X in the SECOND equation
Y in the SECOND equation
4
Multiple Choice
Given the following equation, which variable should you use for substitution and in which equation?
x=4+7y 5x−2y=0X in the FIRST equation
Y in the FIRST equation
X in the SECOND equation
Y in the SECOND equation
5
Multiple Choice
Given the equation below, what should you do to solve the eqation for y?
−4x+y=10
subtract 4x to both sides
add 4x to both sides
subtract 10 on both sides
Equation is already solve for y
6
Multiple Choice
Given the equation below, what should you do to solve the eqation for y?
y−9x = −14
subtract 9x to both sides
add 14 to both sides
subtract 14 on both sides
add 9x on both sides
7
Multiple Choice
Given the equation below, what should you do to solve the eqation for x?
x+2y=10
subtract x to both sides
add 2y to both sides
subtract 2y on both sides
add x on both sides
8
Multiple Choice
Given the equation below, what should you do to solve the eqation for x?
x=10+3y
subtract 10 to both sides
add 3y to both sides
subtract 3y on both sides
the equation is already solved for
9
Multiple Choice
What should you work look like if you use y = 3x +2 and substitute it in for x + y = 10?
x + 2 =10
(3x + 2) + y = 10
x + (3x + 2) = 10
x + 3x = 10
10
Multiple Choice
What should you work look like if you use x = -4x + 1 and substitute it in for 3x - 2y = 4?
(-4x - 1) - 2y =4
(-4x + 1) - 2y = 4
(-4x + 1) = 4
3x - 2(-4x + 1) = 4
