Question

Write five pairs of integers (a,b) such that a+b= -7

Answer 1

1) -3 + -4

2) -1 + -6

3) -5 + -2

4) -12 + 5

5) -15 + 8

Answer 2

Answer:

To Find:

5 pair of integers [a, b] such that a + b = -7.

.....................................................

We have to write in the form of:

$\boxed{\sf{a + b = -7}}$

REMARK: It has two variables, that is, it is a linear equation with 2 variables. The solutions will make a graph where the solution will become always minus 7.

So,

a + b = -7

or, a = -7 - b

NOW, let us find the value of a and b.

1st Solution:

If a is equal to 0 and b is equal to -7, the equation becomes correct.

2nd Solution:

If a is equal to 1 and b equal to -8, the equation is also correct.

3rd Solution:

If a is equal to -8 and b equals to 1, the equation is correct.

4th Solution:

If a equals to 100 and b equals to -107, the equation is correct.

5th Solution

If a is equal to 200 and b equal to -207, the equation becomes correct too.

Required Answer:

5 pairs of integers [a, b] such that $\boxed{\sf{a + b = -7}}$ are:

1. a = 0 ; b = -7.
2. a = 1 ; b = -8.
3. a = -8 ; b = 1.
4. a = 100 ; b = -107.
5. a = 200 ; b = -207.
