Question

Value of x and y 5x+y=1;2x+3y=_1

Answer 1

Answer:

x = 2/13

y = 3/13

Step-by-step explanation:

5x+y=1 ---------(a)

2x+3y=1 -------(b)

using elimination method

multiplying equation (a) by 3 and subtracting it by equation(b)

15x + 3y = 3

2x  + 3y = 1

------------------

13x         = 2   => x = 2/13

substituting value of x in equation (b) we get vale of y as

y = 3/13
