No because it's not a simultaneous equation but some kind of algebraic expression
The GCF is y4
a solution to an equation is the answer
A solution is the answer to an equation.
An equation that has no solution is called an equation that has no solution.
x=y4 /2
In algebraic terms, the solution is the answer to equation.
Every equation has a solution.
4x-y4 what = 0
The solution set is the answers that make an equation true. So I would call it the solution.
You cannot solve it since only one side of an equation is given. If the equation was y4 + 5y2 - 84 = 0 then y4 + 12y2 - 7y2 - 84 = 0 or y2*(y2 + 12) - 7*(y2 + 12) = 0 or (y2 - 7)*(y2 + 12) = 0 then y2 = 7 or y2 = - 12 y = +or- sqrt(7) and, if you are in the complex domain, also y = +or- i*sqrt(12) where i is the imaginary square root of -1.
