Use elimination method to solve
5x+y=-10
7x-3y=-36

Let's multiply the first equation by 3. (As you can see y's coefficient in the first one is 1 and in the second one is -3 , we will multiply the first equation by 3 so when we add the equations their sum will be 0)



Now let's add this new equation and our second equation.



We found x=-3

Now let's plug x's value in one of the equations to find y's value.



So we found y=5

Solution ;

(-3, 5)
