Question

Solve x + 3y = 9
3x – 3y = –13

Answer 1

x=-1, y=10/3

Answer 2

we have many ways to start this problem ,the easiest one is adding
Let x + 3y = 9 be equation 1
and let 3x – 3y = –13 be equation 2
By adding 1+2 u get : x+3y+3x-3y=9+-13
4x=-4
x=-1
now after u got the x value go and substitute in any equation and let it be equation 1 (x+3y=9) put x=-1 , -1+3y=9 , 3y=9+1 ,3y=10 ,y=10/3
