So you have:

1) Start off by multiplying both sides by x to simplify the problem:

2) Now isolate the x by moving all terms with x onto one side and all other terms onto the other side:

3) Finally, divide by 3 on both sides to find the value of x:

------
Answer: x =
1) x+y = 170
x-y = 26
2) Subtract the two equations from each other. Doing this you get 2y = 56.
So the value of y is 28. Then plug in the value of y into any of the two equations and solve for x.
x-28 = 26
x = 54
3) When writing solutions as an ordered pair, the x value always comes first followed by the y value. So it would be (54, 28).
