Question

The equations 4x-5y=5,3x+10y=20,4x-5y=-5 and 3x+10y=-20
Which system of equations has a solution of approximately (–2.7, –1.2)?
A.4x-5y=-5 and 3x+10y=-20
B..4x-5y=5 and 3x+10y=20
c. 4x-5y=5 and 3x+10y=-20
D.4x-5y=-5 and 3x+10y=20

Answer 1

The point (-2.7,-1.2)satisfied the option A

Answer 2

Answer:

hEY mate

Step-by-step explanation:

Point is (-2.7,-1.2) =>x=-2.7,y=-1.2

OPT a eqn are

:4x-5y=4*-2.7-5*-1.2=-4.8=-5 (appx)

2nd eqn :

3x+10y=3*-2.7+10*-1.2=-8.1-12=(-20)(appx)

Since opt a satisfies the eqn so opt a is right
