Inverse Operations
What is the inverse operation for addition?
Subtraction
Solve for y :
8x + y = 5
y = 8x + 5
Solve for x :
x - b = 16
x = b + 16
x
Combine like terms :
3x + 4 (x + 2)
7x + 8
What is the inverse operation of Multiplication?
Division
Solve for y :
3x + 5y = 30
y = 3/5x + 6
Solve for x :
c - x = 5
x = -c - 5
What is the range? x or y
y
Evaluate : 3x + 15y + 6
if x = 4 and y = 2
48
What is the inverse operation of subtraction?
Addition
Solve for y :
-2x - y = 4
y = -2x - 4
Solve for x :
7x - 6b = 24
x= 6b + 24
7
What is the domain? x or y?
x
What is the type of solution?

One
What is the inverse operation for division?
Multiplication
Solve for y
2(5x + y) = 3
y = 5x + 3/2
8x + 4 - 5x = b
x = b - 4
3
