Answer:
The needed equation is :
Explanation:
A variable is defined as the UNKNOWN quantity whose value is determined on the basis of equation in which it is used.
A number or CONSTANT is defined as the KNOWN quantity whose value is NOT BASED on the basis of equation in which it is used.
Foe example C = 3, 5 ,-9,0 ...
Here, let us assume here the variable = m
And let us assume a number to be a CONSTANT C.
So, here Constant number C is multiplied with variable, we get : C x m
Also, the resultant is (-4/5)
So, The statement : a number is multiplied by a variable, and a solution is -4/5 is written as:
Hence the needed equation is
