Solve the equation 6(3x + 4) = 4x − 4.x equals negative ten sevenths
x equals negative four sevenths
x = −2
x = 2

Answers

Answer 1
Answer:

An equation is formed of two equal expressions. The solution of the equation 6(3x + 4) = 4x − 4 is x=-2.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution for the equation is,

6(3x + 4) = 4x − 4

18x + 24 = 4x - 4

18x - 4x = -24 - 4

14x = -28

x = -2

Hence, the solution of the equation 6(3x + 4) = 4x − 4 is x=-2.

Answer 2
Answer:

Answer:

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
