Given Question
The problem can be translated to: IxI = -x.
Procedure
These lead to a system of linear equations
x = -x for x>0….Equation 1
or
x = -(-x) for x<0….Equation 2
From Equation 1 x = 0 which is not accepted since it is given x is a non-zero real number.
From the Equation 2 x = x
Which is valid for all real numbers such that x<0
Conclusion
Therefore we conclude here that x should be a negative real number to have its absolute value equals to its opposite.
you could either multiply straight away or you could simplify right then so that you wouldn't have to it later.
20/5 * 5/2
your answer would be 10 either way
Answer:
9
Step-by-step explanation:
open the bracket, you will have
5x-2x+13=40
collect like terms
5x-2x=40-13
3x=27
divide both side by 3
3x/3=27/3
x=9
