Question

In graph of linear equation 3x + 4y = 60, there is a point such that its ordinate is thrice of abscissa. Find coordinates of the point​

Answer 1

Answer:

(4,12)

Step-by-step explanation:

Let abscissa be x and ordinate be y

3x = y. -(1)

3x +4y =60. -(2)

Substituting Equation 1 in 2

5y = 60

y = 12

x = 4

Therefore the coordinates is (4,12)
