I take the stress out of learning math, and make it seem easy and fun!

Let x = 1st number

Let y = 2nd number

Read the problem and translate into two sets of simultaneous equations, and solve by **elimination:**

6x + 5y = -9 multiply every term of this equation by 5

5x + 8y = 4 multiply every term of this equation by -6

You now have the following equivalent equations where you can eliminate the terms containing **x** and solve for **y.**

30x + 25y = -45

-30x - 48y = -24

0x -23y = -69 (divide both sides by -23)

** y = 3 ** plug in 3 for **y** in either equation and you will find that **x** = -4

** x =** **-4**

Reread the problem and make sure your two solutions make sense...
