Given:
Amount invest p = Tk.x
Number of year t = 4
Rate r = x%
Profit = Tk.x
Find:
Value of x
Computation:
Profit = prt / 100
Tk.x = [(Tk.x)(x)(4)] / 100
x = 100 / 4
x = 25
Answer:
x = 1, y = 2
Step-by-step explanation:
In the elimination method to solve a system of linear equations, one of the two equations is added/subtracted to the other, in order to eliminate one variable from the equation.
In this problem, we have the following two equations:

To solve the system, first we multiply by 2 both sides of the second equation, and we get:

So now the system is

Now we add the two equations, and we get:

So, we get

Now we can substitute this value of y into the eq.(2), and we get:
