The sum of what number and -9 is -3 ?

Let the number be x.

Therefore, by the problem

x + (-9) = -3

or, x -9 = -3

or, x = -3 +9

or, x = 6

The answer is 6.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
