y=0x^{2}+3x+68
Multiply 0 and 6 to get 0.
y=0+3x+68
Anything times zero gives zero.
y=68+3x
Add 0 and 68 to get 68.
68+3x=y
Swap sides so that all variable terms are on the left hand side.
3x=y-68
Subtract 68 from both sides.
\frac{3x}{3}=\frac{y-68}{3}
Divide both sides by 3.
x=\frac{y-68}{3}
Dividing by 3 undoes the multiplication by 3.
y=0x^{2}+3x+68
Multiply 0 and 6 to get 0.
y=0+3x+68
Anything times zero gives zero.
y=68+3x
Add 0 and 68 to get 68.
