3x+18=x-2+5
Use the distributive property to multiply 3 by x+6.
3x+18=x+3
Add -2 and 5 to get 3.
3x+18-x=3
Subtract x from both sides.
2x+18=3
Combine 3x and -x to get 2x.
2x=3-18
Subtract 18 from both sides.
2x=-15
Subtract 18 from 3 to get -15.
x=\frac{-15}{2}
Divide both sides by 2.
x=-\frac{15}{2}
Fraction \frac{-15}{2} can be rewritten as -\frac{15}{2} by extracting the negative sign.
