Equations:
x + y = 71
x - 3y = 3
------
Subtract and solve for "y"::
4y = 68
y = 17
-----
Solve for "x"::
x + 17 = 71
x = 54

You can put this solution on YOUR website! a+b=71, therefore a=71-b
b-3a=3
b-3(71-b)=3
b-213-3b= 3
-2b= -210
b= -210/-2
b= 105 Now go back to the original formula:
a+105= 71
a= 71-105
a= -34 This is b. Let's try it in the problem. It says that the sum is 71:
105+(-34)= 71
Now the problem says, if three times the smaller number is subtracted from the larger number, the result is 3
3*34= 102; 105-102= 3
We've got the right answers.
