Answer :
The equation which is equivalent to the given expression is 4x + y = 21.
What is an expression?
Expression is a finite combination of symbols that is well-formed according to rules that depend on the context. An expression is a combination of numbers, variables, or a combination of numbers and variables, and symbols and it is connected by the sign of equal.
We have,
Expression [tex]\frac{12x^4(x-3)(x+5)}{30x(x+3)(x+5)}[/tex]
So,
Now,
To get the equivalent expression,
Cancel the common factor (x + 5) of the given expression,
On solving,
We get,
[tex]\frac{12x^4(x-3)}{30x(x+3)}[/tex],
Now,
On solving further,
We get,
[tex]=\frac{2x^3(x-3)}{5(x+3)}[/tex]
So, We can not solve it further,
So, This is the expression that is equivalent to the given expression.
Hence, we can say that the equation which is equal to the given expression is [tex]\frac{2x^3(x-3)}{5(x+3)}[/tex].
