One equation with two unknowns usually does not have a solution.
There can be no solution set because there is no equation or inequality, only an expression.
Since that isn't an equation, there is really nothing to solve.
For example if x3 = 27 then cube root both sides gives the solution of x = 3
x3-y3

For example if x3 = 27 then cube root both sides gives the solution of x = 3
x3-y3
-x(x - 99)(X + 27) x = 0, -27, 99
x3
The equation 3 by 3 is 9. This is a math equation.
A line graph needs an equation. x-2 and x3 are expressions: neither is an equation.
y2=x3+3x2
a solution to an equation is the answer
x3+13x2=-22xadd 22x to both sides:x3+13x2+22x=0now factor:x(x2+13x+22)=0x(x+11)(x+2)=0x=0x+11=0x+2=0Therefore the solution to this equation is x=0, x=-11, x=-2
