Sum of two number s is 215 and their difference is 53 .find the numbers

Answer 1

a = first number

b = second number

Sum of two number s is 215 mean:

a + b = 215

Their difference is 53 mean:

a - b = 53

Now you must solve system of two equation with two unknown::

a + b = 215

a - b = 53

Try that.

The solutions are:

a = 134 , b = 81

Prof:

a + b = 134 + 81 = 215

a - b = 134 - 81 = 53
