Determine the point on the graph of the linear equation 2x + 5y = 19 whose ordinate is times its abscissa.
Given: 2x + 5y = 19…………(i)
ordinate is times its abscissa
⇒ y = x = x
Putting y = x in eq. (i)
2x + 5 x = 19
Putting x = 2 in eq. (i)
2x2 + 5y = 19
y = = 3.
Therefore point (2, 3) is the required solution.
