-x-\left(-2\right)=3\left(2x+3\right)
To find the opposite of x-2, find the opposite of each term.
-x+2=3\left(2x+3\right)
The opposite of -2 is 2.
-x+2=6x+9
Use the distributive property to multiply 3 by 2x+3.
-x+2-6x=9
Subtract 6x from both sides.
-7x+2=9
Combine -x and -6x to get -7x.
-7x=9-2
Subtract 2 from both sides.
-7x=7
Subtract 2 from 9 to get 7.
x=\frac{7}{-7}
Divide both sides by -7.
x=-1
Divide 7 by -7 to get -1.
