777dan777 [17]

Answer: $x=2/5$ or $x=0.4$

Simplify the equation to the form

$6x-2=-4x+2$

Move all terms containing x to the left and all other terms to the right

$6x+4x=+2+2$

Simplify left and right side of the equation

$10x=+4$

Divide both sides of the equation by 10 to get x

$10x/10=4/10$

$x=2/5$ or $x=0.4$
