The Sum Of Two Numbers Is 170 And Their Difference Is 26. Find The Two Numbers. Write The Solution Of This As An Ordered Pair?

X + y = 270
x - y = 26
Add the two equations:   2x = 296
  x = 148
Substitute this value of x back into either of the original equations and solve for y:
148 + y = 270
  y = 122
An ordered pair might be (148, 122)
