Set this up as a system of equations.
x + y = 60
x - y = 3
Solve for either x or y in one of the equations. It doesn't matter what you choose.
I'll solve for x in equation 2.
x - y = 3
x= y + 3
Now plug y + 3 in for x in the first equation. You get:
y + 3 + y = 60
Sove for y.
2y + 3 = 60
2y = 57
y = 28.5
Now plug this value into either equation and solve for x. I'll use equation 2.
x - 28.5 = 3
x = 31.5
So your answers should be 31.5 and 28.5.

There is no way to write any one or more of those six digits in such a way as to equal 47.
The difference between two positive numbers is 5 and the sum of their squares is 233 what are the numbers?
Those numbers would be 13 and 8. 13 squared + 8 squared This is equal to: 169 + 64 which equals 233 And finally, 13 - 8 equals 5.
What two numbers equals to 46 and when you multiply those two numbers it equals 100?

What those 2 2 equal?
It5 equals 4.
What times what equals 120 but when added equal -7?
There aren't two whole numbers that will satisfy those conditions. If that's -120, you can use -15 and 8.
Is it possible 10 plus 20 equals 80?
Not with those numbers
What times what equals 42 and those numbers equal negative 5. What are the numbers?
The factor pairs of 42 are (42,1)(21,2)(14,3)(7,6) Even considering their negative counterparts, none of them add up to -5.
