## The 6 steps to solving a 2-variable equation:

**5a + 2b = 3 **

4a + 5b = 6

1) Find **a **on its own:

**a = (3-2b)/5 **

2) Substitute into the other equation:

** 4((3-2b)/5) + 5b = 6 **

3) Multiply (only if there are fractions):

**4(3-2b) + 25b = 30 **

4) Distribute:

**12 - 8b + 25b = 30**

5) Combining like terms:

**17b = 18**

6) Divide

** b = 18/17 **

AND YOU'RE DONE!!! :D
