Solve for the variable y (move the x to the right of equal with changed sign)
M is the coefficient before the x and b is the known number
-3y = -12 - 6x
Since the y can't be negative, multiply every term for -1, therefore change their sign
3y = 6x + 12
To find y, divide both terms for 3
y = 2x+4
Therefore your answer is y = 2x+4

Answer:
8.8 cm
Step-by-step explanation:
-We know that the top 20% of the books are oversized.
-We therefore find the z-value of the top 20%:
#We substitute the z value in formula to solve X.
Where
- X is the minimum thickness of the book.
-Given , the minimum thickness,X can be calculated as follows:
Hence, the minimum thickness of the oversized books is 8.8 cm
