7x-x_{5}^{2}\times 9x=0
Subtract x_{5}^{2}\times 9x from both sides.
7x-9x_{5}^{2}x=0
Multiply -1 and 9 to get -9.
\left(7-9x_{5}^{2}\right)x=0
Combine all terms containing x.
x=0
Divide 0 by 7-9x_{5}^{2}.
7x-x_{5}^{2}\times 9x=0
Subtract x_{5}^{2}\times 9x from both sides.
7x-9x_{5}^{2}x=0
Multiply -1 and 9 to get -9.
\left(7-9x_{5}^{2}\right)x=0
Combine all terms containing x.
x=0
Divide 0 by 7-9x_{5}^{2}.
