Randomly assigned group. the art class isn't random and only consists of a select type of people--it is not a representative sample; maybe more left handed people enjoy art than do right handed people! therefore, even though the randomly assigned group is smaller, it is the better estimate.

X + 2 = 5x + 26<br><br> Please help

kkurt [141]

$x+2=5x+26$

Move all the x's to one side of the equation. This is a step necessary to solve this equation.

Subtract both sides by x.

$x+2-x=5x+26-x$
$2=4x+26$

Flip equation. We always want to have the variable written on the left side.

$4x+26=2$

Subtract both sides by 26.

$4x+26-26=2-26$
$4x=-24$

Divide both sides by 4 to finish this off.

$x=-6$

That's your answer. Have an awesome day! :)
