Question 164775
the sum of two numbers is -3. if the second number is subtracted from the first, the difference is 27. find the numbers
:
x + y = -3
x - y = 27
----------------addition eliminates y, find x
2x = 24
x = 12
:
Find x using the 1st equation
12 + y = -3
y = -3 - 12
y = -15
:
Check solutions in the 2nd equation
12 - (-15) = 27
