$x = 3$ $x=3$

First you need to add $3$ $3$ to both sides,

$- 3 + 3 x + 3 = - 2 x + 12 + 3$ $-3+3x+3=-2x+12+3$

$3 x = - 2 x + 15$ $3x=-2x+15$

Then you need to add $2 x$ $2x$ to both sides.

$3 x + 2 x = - 2 x + 15 + 2 x$ $3x+2x=-2x+15+2x$

$5 x = 15$ $5x=15$

The last step is to divide both sides by 5,

$5 x \div 5 = 15 \div 5$ $5x-: 5=15 -:5$

$x = 3$ $x=3$

How do you solve -3+ 3x = - 2x + 12−3+3x=−2x+12-3+ 3x = - 2x + 12?
