What is the solution to 2(-4x+1)=2/3(x+2)
Rzqust [24]

Hello!

The answer to your problem is: x=1/13

<u>Simplify both sides of the equation</u>

(2)(-4x)+(2)(1)=(2/3)(x)+(2/3)(2) (Distribute)

-8x+2=2/3x+4/3

<u>Subtract 2/3x from both sides</u>

-8x+2-2/3x=2/3+4/3-2/3x

-26x+2=4/3

<u>Subtract 2 from both sides</u>

-26/3x+2-2=4/3-2

-26/3=-2/3

<u>Multiply both sides by 3/(-26)</u>

(3/26)*(-26/3x)=(3/-26)*(-2/3)

<u>Get your answer</u>

x=1/13

Hope This Helps!
