Question

Determine the point from the graph of linear equation 2x + 5y = 21 whose abscissa is twice
of its ordinate.

Answer 1

Answer:

Point=(7/3,14/3)

Step-by-step explanation:

2x+5y=21

Abscissa=x

Ordinate=y

Given:- Absiscaa=2(ordinate)

x=2y

2x+5y=21

2(2y)+5y=21

9y=21

y=21/9

y=7/3

x=2y=14/3

(x,y)=(7/3,14/3)
