Solve for the value of x 3x - 9 + 12 - 6x = -18
Daniel [21]

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

Jabari is thinking of three numbers. The greatest number is twice as large as the least number. The middle number is three more
Masteriza [31]

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.
