Answer:
Step-by-step explanation:
We can write the information as equations. We will use variables x and y to find the two numbers
Equation 1: The sum of two numbers is 526
x + y = 526
Equation 2: The difference is 176
x - y = 176
With two variables and two equations, we can first find one variable by elimination:
(See image)
and then substitute y into either equation to find x:
