▹ Answer

x = 1

▹ Step-by-Step Explanation

2(10 - 2x) = 4(3x + 1)

Simple terms are written last:

2(-2x + 10) = 4(3x + 1)

Distributive Property:

-2 * 2x + 2 * 10 = 4 * 3x + 4

x = 1

Hope this helps!

Answer:


\boxed{x=1}

Explanation:


2(10-2x) = 4(3x + 1)


\sf Expand \ brackets.


20 - 4x = 12x + 4


\sf Subtract \ 12x \ and \ 20 \ from \ both \ sides.


20 - 4x - 12x - 20 = 12x + 4 - 12x - 20


-16x = -16


\sf Divide \ both \ sides \ by \ -16.


\displaystyle (-16x)/(-16) =(-16)/(-16)


x=1
