The number of equation/s that are needed in order to solve the problem is equal to the number of the varying variables involved. In this regard, we would say that to solve for 1 unknown variable, only 1 equation is needed. 

For number of variables greater than 1, as stated above, the number of equations should be equal to that number. However, it has to be noted that the equations should be independent and not the multiplicative of another. 

For the concept of multiplicity,

x + y = 0 and 2x + 2y = 0 are just the same equations. 

Hence, the answer to this item is one (1).

DerKrebs [107]

Answer:

The length of the base of the rectangle is 7 inches

Step-by-step explanation:

The Area of the rectangle can be found out by multiplying length with the breadth

Area= length *  breadth

35 squared inches= x *5

5x= 35

x= 35/5

x= 7inches

Hence the length of the base of the rectangle is 7 inches.

If the area and one side are known then we can simply find the 2nd side by simply substituting x in its place and solving the equation.
