Solve the equation 6(3x + 4) = 4x − 4.

x equals negative ten sevenths
x equals negative four sevenths
x = −2
x = 2

x = - 2

Step-by-step explanation:

Given

6(3x + 4) = 4x - 4 ← distribute parenthesis on left side

18x + 24 = 4x - 4 ( subtract 4x from both sides )

14x + 24 = - 4 ( subtract 24 from both sides )

14x = - 28 ( divide both sides by 14 )

x = - 2

x = -2

Step-by-step explanation:

6(3x + 4) = 4x − 4

Distribute:

18x + 24 = 4x - 4

18x - 4x + 24 = -4

14x + 24 = -4

14x = -4 - 24

14x = -28

x = -28 / 14

x = -2

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
