Given :
A system of equations y = 5.69x + 25 and y = 9.49x + 6.
To Find :
The solution of the system of equation.
Solution :
Subtracting equation 2 by 1, we get :
y - y = ( 9.49x + 6 ) - ( 5.69x + 25 )
0 = 3.8x - 19
x = 5
Putting value of x in equation 1, we get :
y = (5.69×5) + 25
y = 53.45
Therefore, the solution of the system of equations is ( 5, 53.45 ).
