The subtraction of equality.

A proper question would help.

If you mean: 14x = 35 then the value of x is 2.5

The multiplicative property of equality. Multiply each side by -1/3.

To solve an equation you would have to follow P.E.M.D.A.S. which leads to the answer. P- parenthesis E- exponents M-multiplication D-division A-addiction S-subtraction

None. Properties of inequalities are not that relevant when solving equalities.

it is the number you would use to solve the problem

Solving implies you are talking about an equation. Equations must have equal marks in them somewhere. If you mean y + 12 = -8then subtract 8 from both sides of the equation ( or if your teacher is really strict you will be told to add -12 to both sides of the equation, but the same thing happens)y + 12 - 12 = -8 - 12, then on the left and right simplify toy = -20This is called the subtraction property of equality (if you subtract 12) or the addition property of equality (if you add -12)

If: 3z = 0.45 Then: z = 0.15 by dividing both sides by 3

Simplifying an equation often helps solve it.

There was no word problem, so it would be a null equation.

if the equation was 7x = 42. The answer would be x = 6

You solve the equation the same way as you would any other equation. Whether the variable is a fraction or otherwise will only become clear once you solve the equation. In other words, you don't initially KNOW whether the solution will be a fraction or not.

That would be the associative property. The associative property applies to addition and multiplication, but not to subtraction or division.

It is used to solve quadratic equations that cannot be factored. Usually you would factor a quadratic equation, identify the critical values and solve, but when you cannot factor you utilize the quadratic equation.

You cannot solve n + 412 because it is an expression NOT an equation (or inequality).

no the equation is not correct, the only way it would be correct is if x=7 which would be a commutative property

The first step would be to find the equation that you are trying to solve!

You would take 2 and replace it for x in your other equation and solve.

l9xl - 3 > 6 Is the equation.

There is no equation (or inequality) in the question. Consequently there is nothing that can be solved.
