Solve for y
y=\left(10-x\right)\left(2x-1\right)
Solve for x (complex solution)
x=\frac{-\sqrt{361-8y}+21}{4}
x=\frac{\sqrt{361-8y}+21}{4}
Solve for x
x=\frac{-\sqrt{361-8y}+21}{4}
x=\frac{\sqrt{361-8y}+21}{4}\text{, }y\leq \frac{361}{8}

21x-2x^{2}-10=y
Use the distributive property to multiply 2x-1 by 10-x and combine like terms.
y=21x-2x^{2}-10
Swap sides so that all variable terms are on the left hand side.
