The sum of 2 integers is 39, and their difference is -203.

What are the two integers?

x + y = 39

x - y = -203

2x = -164

x = -82

y = 121

LET THE NUMBERS BE  X  AND Y

X+ Y = 39

X- Y = -203

2X = -174

X = - 87

SUBSTITUTE  VALUE IN ANY EQUATION

-174 +Y = 39

Y= 213

ANSWER X= -174   ,  Y = 213

Without variables, we can find

the big number=[39+(-203)]/2=-82.

the smaller number=[39-(-203)]/2=121.

The sum of 2 integers is 39

x + y = 39

and their difference is -203

x - y = -203

solve using substitution method

x - (39-x) = -203

x = -82

Z2=39-Z1

Z1-Z2=-203

Z1-39+Z1=-203

2(Z1)-39=-203

2(Z1)=-164

Z1=-82

Z2=39+82=121

Thus, -82+121=39

and, -82-121=-203

-82 and 121

Let x = integer 1

Let y = integer 2

The sum is 39:

x + y = 39

The difference is -203:

x - y = -203

System of two equations and two unknowns.  Solving with elimination, add the two equations together:

x + y = 39

x - y = -203

----------------

2x = -164

x = -82

Now we have x, we can solve for y:

x + y = 39

-82 + y = 39

y = 121

-82 and 121

x - y = -203

2x = -164

x = -82

substitute into x + y = 39

y - 82 = 39

y = 101

Let the 2 integers be A & B.;

A + B =    39...(1).;

A -  B + -203...(2).;

[(1)-(2)]---> 2B = 242, ie., B = 121. Then (1)---> A = 39 - 121 = -(121-39) = - 82.

Let the integers by 'm' & 'n'

Hence

m + n = 39

m - n = -203

2m = -164

m = -82

Henc

-82 + n = 39

n = 39 + 82

n = 121
