Question

the sum of two integers is -30 if one of them is 15 determine the other pls give expalintion

Answer 1

Answer:

(- 45)

Step-by-step explanation:

1 integer = 15

Let the other one be "x"

ATQ: 15 + x =(- 30)

=> x = (- 30 + (- 15)) [by bringing LHS to RHS the sign of 15 changes from plus to minus)

=> x = (-30-15) ...... x = (- 45)

To verify:   15 + (- 45) ..... = 15 - 45... = -30

∴ The other integer is (- 45)
