$x = 0.1$ $x=0.1$

Explanation:

First, add $x$ $color(red)x$ to both sides.

$2 x + x + 3 = - x + x + 3.3$ $2x+color(red)x+3= -x+color(red)x+3.3$

Now combine the $x$ $x$ terms.

$3 x + 3 = 3.3$ $3x+3 = 3.3$

Subtract $3$ $color(blue)3$ from both sides.

$3 x + 3 - 3 = 3.3 - 3$ $3x+3-color(blue)3=3.3-color(blue)3$

Now simplify.

$3 x = 0.3$ $3x = 0.3$

Finally, divide both sides by $3$ $color(orange)3$ .

$3 x \div 3 = 0.3 \div 3$ $3x div color(orange)3 = 0.3 div color(orange)3$

$XXX x = 0.1$ $color(white)"XXX"x = 0.1$
