Question

3x - 4y - 15 = 0 .......... (1)
y +x+ 2 = 0 .......(II)​

Answer 1

Answer:

x = 1 y= -3

Step-by-step explanation:

3x-4y=15..........(1)

X+y=-2..............(2)

Multiple equation (2) by 3,

3x-4y=15

3x+3y=-6

By elimination method

-7y = 21

OR y = -3

putting this value of y in second equation

x+y = -2

X+(-3) =-2

x-3= -2

x=1

x= 1
