Question 91964
2x +3y = 1
5x +3y =16

multiply the first equation by -1

-2x - 3y = -1

add to second equation:

we get  3x = 15

so  x = 5

substitute x in the first equation with 5 to solve for y

{{{2*5 + 3y = 1}}}

10 + 3y = 1

solve this one variable equation

y = -3

so the answer is  x = 5
                  y = -3
