Solve for x: 2/7(x-2)=4x
lawyer [7]

Answer:

x =  -  \frac{2}{13}

Step-by-step explanation:

Simplify to:

\frac{2(x - 2)}{7}

Multiply both sides by 7

2(x-2)=28x

Divide both sides by 2

x-2=14x

Subtract x from both sides

2=14x-x

Simplify 14x-x to 13x

2=13x

Divide both sides by 13

-  \frac{2}{13}  = x

Answer:

x =  -  \frac{  2}{13}
