Answer:
x =7
Step-by-step explanation:
3x - 9 + 12 - 6x = -18
Combine like terms
-3x +3 = -18
Subtract 3 from each side
-3x +3 -3 = -18 -3
-3x = -21
Divide each side by-3
-3x /-3 = -21 /-3
x =7
Answer:

Step-by-step explanation:


<h3>
Apply the quadratic formula with a=3, b=-5 and c=1</h3>
The least number is 18, the middle number is 21 and the largest number is 36.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
Let x represent the least number, y represent the middle number and z represent the greatest number.
The greatest number is twice as large as the least number. Hence:
z = 2x
2x - z = 0 (1)
The middle number is three more than the least number, hence:
y = x + 3
x - y = -3 (2)
The sum of the three is 75, hence:
x + y + z = 75 (3)
From the three equations:
x = 18, y = 21, z = 36
The least number is 18, the middle number is 21 and the largest number is 36.
