How would you solve this?

anonymous · Answer

Would the 2 numbers be 98 and -72 ?

anonymous · Answer

x+y=170, y-x=26
y-x=26
y=26+x
x+26+x=170
2x+26=170
2x=170-26
2x=144
x=72
x+y=170
72+y=170
y=170-72
y=98.

The numbers would be 98 and 72.  You can solve this by using simultaneous equations:

x + y = 170
x - y = 26

Now add the two equations to get:

2x = 196
x = 98

Now substitute x=98 into one of the equations to get the other number--for example,

x + y = 170
98 + y = 170
y = 72
