Question

The sum of two numbers is 170 and their difference is 26. Find the two numbers. Show how to solve this using any method.

Answer 1

Let the two nos be x and y
x+y= 170
x-y=26 cross out the y
2x=196
x=98

y= 170-98
y= 72

Answer 2

The sides of a triangle have measures of x, x, and y, and the perimeter of the triangle is 46. The measure y is 4 centimeters longer than the measure x.
Write the solution for this as an ordered pair.
