Question

Write the equation 2x −4 = 4x + 4 in two variables​

Answer 1

Step-by-step explanation:

Simplifying

2x + 4 = 4x + -4

Reorder the terms:

4 + 2x = 4x + -4

Reorder the terms:

4 + 2x = -4 + 4x

Solving

4 + 2x = -4 + 4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4x' to each side of the equation.

4 + 2x + -4x = -4 + 4x + -4x

Combine like terms: 2x + -4x = -2x

4 + -2x = -4 + 4x + -4x

Combine like terms: 4x + -4x = 0

4 + -2x = -4 + 0

4 + -2x = -4

Add '-4' to each side of the equation.

4 + -4 + -2x = -4 + -4

Combine like terms: 4 + -4 = 0

0 + -2x = -4 + -4

-2x = -4 + -4

Combine like terms: -4 + -4 = -8

-2x = -8

Divide each side by '-2'.

x = 4

Simplifying

x = 4

Answer 2

Step-by-step explanation:

$\tt \red{ \implies2x - 4x = 4 + 4}$

$\tt \pink{ \implies - 2x = 8}$

$\tt \blue{ \implies x = - \dfrac{8}{2} }$

$\red{\boxed{ \boxed{\boxed{ \boxed{\boxed{ \boxed{\boxed{ \boxed{ \boxed{ \boxed{ \tt \orange{ \implies \: x = - 4}}}}}}}}}}}}$
