x=21+3\left(2x+1\right)
Combine 2x and -x to get x.
x=21+6x+3
Use the distributive property to multiply 3 by 2x+1.
x=24+6x
Add 21 and 3 to get 24.
x-6x=24
Subtract 6x from both sides.
-5x=24
Combine x and -6x to get -5x.
x=\frac{24}{-5}
Divide both sides by -5.
x=-\frac{24}{5}
Fraction \frac{24}{-5} can be rewritten as -\frac{24}{5} by extracting the negative sign.
