13-\left(3x-1\right)\times 3=2y-\left(3x+2\right)^{2}
Multiply 3 and 1 to get 3.
13-\left(9x-3\right)=2y-\left(3x+2\right)^{2}
Use the distributive property to multiply 3x-1 by 3.
13-9x+3=2y-\left(3x+2\right)^{2}
To find the opposite of 9x-3, find the opposite of each term.
16-9x=2y-\left(3x+2\right)^{2}
Add 13 and 3 to get 16.
16-9x=2y-\left(9x^{2}+12x+4\right)
Use binomial theorem \left(a+b\right)^{2}=a^{2}+2ab+b^{2} to expand \left(3x+2\right)^{2}.
16-9x=2y-9x^{2}-12x-4
To find the opposite of 9x^{2}+12x+4, find the opposite of each term.
2y-9x^{2}-12x-4=16-9x
Swap sides so that all variable terms are on the left hand side.
2y-12x-4=16-9x+9x^{2}
Add 9x^{2} to both sides.
2y-4=16-9x+9x^{2}+12x
Add 12x to both sides.
2y-4=16+3x+9x^{2}
Combine -9x and 12x to get 3x.
2y=16+3x+9x^{2}+4
Add 4 to both sides.
2y=20+3x+9x^{2}
Add 16 and 4 to get 20.
2y=9x^{2}+3x+20
The equation is in standard form.
\frac{2y}{2}=\frac{9x^{2}+3x+20}{2}
Divide both sides by 2.
y=\frac{9x^{2}+3x+20}{2}
Dividing by 2 undoes the multiplication by 2.
y=\frac{9x^{2}}{2}+\frac{3x}{2}+10
Divide 20+3x+9x^{2} by 2.
