5/9 x 45 = 25
45 and 25 are both integers, not fractions. 45 * 5/9 = 25.
There are infinitely many solutions as x + y = 45 defines a straight line. Pick a value for x and you can calculate the y value so that x + y = 45. It can be rearranged to get y in terms of x: x + y = 45 → -x + x + y = -x + 45 → y = -x + 45 It is a line with slope -1 and intercept 45. You can substitute any value for x and the corresponding y value will be found. eg x = 1 → y = -1 + 45 = 44 x = 25 → y = -25 + 25 = 20
