Question

x - 3y = 1 ; 3x - 2y + 4 = 0​

Answer 1

Step-by-step explanation:

x - 3y = 1

x = 1 + 3y -----------(1)

3x - 2y = -4

3x = -4 + 2y

x = -4 + 2y / 3 --------(2)

from equations (1)&(2)

1 + 3y = -4 +2y /3

3 + 9y = -4 + 2y

7 = 2y - 9y

7 = -7y

y = -1

if y = -1

x - 3 (-1) = 1

x + 3 = 1

x = - 1
