four times a first number decreased by three times a second number is 22. the sum of the first number and twice the second number 0
-------
1st: a
2nd: b
--------------------------
Equations:
4a-3b = 22
a + 2b = 0
------------------
Substitute for "a" and solve for "b":
4(-2b)-3b = 22
-11b = 22
b = -2
-----
Solve for "a":
a = -2b
a = -2*-2 = 4
