D.First Number is 40 and second number is 160

We Gonna -45 -5

In we Gonna + the 125

c) the first number is 85, the second number is 40.

Step-by-step explanation:

let:

first number= x

second number=y

(equation 1) x+y = 125 and;

(equation 2) x-y= 45

let us get equation 2 values in terms of x.

x-y= 45

x= 45+y ---> substitute this to equation 1 to get value of y.

x+y=125

(45+y) +y=125

45+y+y= 125

2y=125-45

2y=80

y=40 ----- THIS IS THE SECOND NUMBER

substitute the 2nd number to equation 2.

x-y=45

x-40=45

x=45+40

x=85----> THIS IS THE FIRST NUMBER.

thus, c) the first number is 85, the second number is 40.
