Answer:
x = (c+a)/2
y = (c-a)/2
Step-by-step explanation:
Add the two equations and you get ...
(x +y) +(x -y) = (c) +(a)
2x = c+a
x = (c+a)/2
--
Subtract the second equation from the first and you get ...
(x +y) -(x -y) = (c) -(a)
2y = c-a
y = (c-a)/2

This is what I call a "sum and difference" problem. The solution shown here is (obviously) the generic solution to such a problem. Remembering this can get you quickly to the answer any time you're given the sum of two unknowns and their difference.

Answer:
$154
Step-by-step explanation:
First, we need to find out how much Dale will make for 1 hour of work which means we need to divide $252 by 18 which is 14. Next, to find out how much he will make for 11 hours at work, we need to multiply 11 by 14 which is $154.
Here are the equations:
$252÷18=$14
$14×11=$154
