Find the point (x1,x2) that lies on the line x1 +5x2 =7 and on the line x1 - 2x2 = -2.
Savatey [412]

Given :

Two equation x_1 +5x_2 =7 and x_1 - 2x_2 = -2 .

To Find :

The point of intersection of these lines .

Solution :

We will use elimination method :

From equation 1 :

x_1=7-5x_2

Putting value of x_1 in equation 2 we get :

(7-5x_2)-2x_2=-2\\\\7-7x_2=-2\\\\x_2=\dfrac{9}{7}

Putting value of x_2 in equation 1 we get :

x_1+5\times \dfrac{9}{7}=7\\\\x_1=\dfrac{4}{7}

Therefore , point of interaction is (\dfrac{4}{7},\dfrac{9}{7}) .

Hence , this is the required solution .
