Answer:
So we know the sum of two numbers, let them be x and y, is equal to 36:
x + y = 36
And on of them, for example, y, is equal to 10:
x + 10 = 36
Now, the only thing we need to do is solving the equation to find x:
x + 10 = 36
We pass the 10 substracting to the right:
x = 36 - 10
And now, we substract:
x = 26
Now we know one number is 10 and the other is 26, so we can verify we have done all correctly
26 + 10 = 36 (TRUE)
Now we know we have done the exercise well.
