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).

<span>3x+5y= 12
5y = 12 -3x
y = (12-3x)/5
y = 12/5 - 3x/5
y = 2.4 -0.6x
or
y = -0.6x + 2.4</span>
