Question

X =1 Y = -1 is a solution of the system of linear equation 2 X + 5 Y = 3 and x- 3 Y = 4.

Answer 1

Step-by-step explanation:

x-3y:4

substitute the values of the variables

1-3(-1):4

1-(-3):4

1+3:4

4:4

Answer 2

Step-by-step explanation:

2X + 5Y =3 .....(1)

X - 3Y =4 .....(2)

multiply equation (2) by 2 and subtract,

2X +5Y = 3

2X - 6Y =8
