When solving an equation why do you apply the inverse on
 the given operation to both sides

Answers

Answer 1
Answer:
You can do anything you want to one side of an equation.
You'll usually apply an inverse operation to make the side
simpler, for example to get rid of the 'x', or to get rid of the
fractions on that side.

But when you do something to one side of the equation,
you MUST do exactly the same thing to the other side too.
If you don't, then you have changed the equation to a
different one, and the solution to the one you have now
is not the solution to the original one.

Very simple example:

Solve the equation            2x = 2

Correct solution:
Divide each side by  2 :      x = 1

Incorrect solution:
Divide the left side by  2 :    x = 2

-3.75 into a fraction

Answers


-3 (3)/(4)
is the answer bc .25/100 = 1/3 so .25×3 is 75 and 75/100 = 3/4
75÷25 = 3 and 100÷25=4

Ignore the negative sign for now.

3.75

Split the number into its whole number component and decimal component

3.75 = 3 + 0.75

For the decimal component, 0.75 is the same as 75/100

75/100

Find the GCF (Greatest Common Factor) of 75, 100

GCF = 25

Divide both the numerator and the denominator by the GCF

75 ÷ 25/100 ÷ 25

Simplify

3/4

Combine the whole number component with the fraction

3 3/4

Add the negative sign back

-3 3/4
