Question

Solve the given pair of equations 2x + 5y = 1 & 3x - y = 8​

Answer 1

Answer:

36/7, - 13/7

Step-by-step explanation:

First equation = 2x+5y=1

3x-y=8

Multiplying first by 3 and second by 2 we get

6x+15y=3 --(1)

6x-2y=16 - - - (2)

(1)-(2):

17y= -13

y= - 13/17

2x+5(-13/7) = 1

2x - 65/7 = 1

2x = 1+65/7

2x = 72/7

X = 72/7×1/2

X = 36/7
