Solve the equation

- 9x – 2y=-12
2x+5y=-11

X=
Y=

x=2, y=3

Step-by-step explanation:

solving this equation simultaneously

-9x - 2y=-12(1)

2x + 5y=-11.. (2)

Using elimination method

Multiply equation 2 by 2 and equation 1 by 5

-45x -10y= -60(3)

4x + 10y=-22(4)

Subtracting equation 2 from 1

-41x + 0=-82

41x=82

x=82/41

X=2

To find y put x in equation 1

-9x - 2y= -12

-9(2)-2y=-12

-18-2y=-12

-2y=-12+18

-2y=6

Y= 6/2

Y=3

X=2, Y=3
