x + y = 43   The sum of two numbers.

x - y = 19    The difference of two numbers.

Add the two equations together.

2x = 62

x = 31

substitute into first equation and solve for y

31 + y = 43

y = 43 - 31

y = 12

x = 31, y = 12

one number is equal to the square of another. Find the numbers if both are positive and their sum is 12

Two angles have a sum of 96°. Their difference is 18°. Find the angles
by
a+b=43
a-b=19

so 2a = 43+19=62

and then a=31
and b=12
by

Sum equation                    x + y = 43

Difference equation          x - y = 19

Now add equations         2x     = 62  ( the y variable cancels out)

Now solve for x                  x =    31

Finally plug the value of x into one of the origianl equations to find y

31 + y = 43   so y = 12

Suppose the smaller one is now equal to the larger, then their sum of these two will be 43 + 19 = 62. This is the summer of two larger, therefore the larger number is half of 62 = 31. The smaller one is 31 - 19 = 12.

Let X and Y are two numbers then X + Y = 43 --------(sum of two number) X - Y = 19 --------(difference of two number) ----------------------------------------------- 2X =62 => X=31 31 + Y = 43 => Y=12 Ans = 31, 12

x+y=43 x-y=19 ---------- 2x = 62 ---------- x=31 substitute 31+y=43 y=43-31 y=12
