Question 238677
Here's one I just did, see if you can do it like this.
If you have trouble, or to check your work, email me at

Solve the system by the elimination method.
5x + 5y = -13
7x - 3y = 19 
-------------
To eliminate one of the variables, multiply one or both eqns to get the same coefficient for one of them. You can do either, I'll do y
--------
5x + 5y = -13 x3 --> 15x + 15y = -39
7x - 3y = 19 x5 --> 35x - 15y = 95
--------------------------------------
15x + 15y = -39
35x - 15y = 95
--------------- Add
50x = 56
x = 56/50 = 1.12
-----------------
Usually it's "elimination and substution", once you find one, you can sub and find the others.
7x - 3y = 19
7*1.12 - 3y = 19
3y = 7.84 - 19 = - 11.16
y = -3.72
