Question

Solve tha following pair line equation x-2y=8 ;x-3y=13solve tha following pair line equation x-2y=8 ;x-3y=13

Answer 1

Answer:

Hence the value of

$x = - 2 \\ y = - 5$

Step-by-step explanation:

$x - 2y = 8 ...........(1) \\ x - 3y = 13.........(2)\\ subtract \: eq.(1) \: from \: eq.(2) \\ x - 3y = 13 \\ - (x - 2y = 8) \\ x - 3y - x + 2y = 13 - 8 \\ - y = 5 \\ y = - 5$

$put \: the \: value \: o f\: y \: in \: eq.(1) \\ x - 2y = 8 \\ x - 2 \times ( - 5) = 8 \\ x + 10 = 8 \\ x = - 10 + 8 \\ x = - 2$
