Question

The sum of two number is 137 and thire difference is 43.find the number

Answer 1

x + y = 137
x - y = 43
Add both equations
2x = 180 
x = 90
90 - y = 43
y = 90 - 43
y = 47

Answer 2

The two numbers are 90and 47
X+Y=137
X-Y=43
By adding the above two, we get
2X=180
X=180/2
X=90
Hence by substituting the value of X in the equation we get Y=47
°. ° Hence the two numbers are 90and 47
