The addition of the opposite, to both sides of the equation. keep it equal
Isolate the variable. Get it by itself. 9+11x=89+x 9+11x-1x=89+x-1x Subtraction property of equality 9+10x=89 9+10x-9=89-9 subtraction property of equality 10x=80 x=8 division property of equality.
That means that subtracting the same value or expression from both sides of an equation is a valid operation, in the sense that the new equation will have the same solution set. The definitions of "addition property...", "multiplication property..." and "division property..." are similar; with the main caveat that you may not multiply or divide by zero.
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)
in an equation like y=5x+3 the 3 would be the y-intercept
The subtraction of equality.
The addition of the opposite, to both sides of the equation. keep it equal

The addition property of equality states that if you add the same number to both sides of an equation, then the sides remain even. This means that the equation remains to be true.
The properties are similar in that they function the same way, but they are not interchangeable. If you add to one side of the equation, you have to add to the other. If you subtract from one side of the equation, you have to subtract from the other.
if an equation is simplified by removing parentheses before the properties of equality are​ applied, what property is​ used?
The multiplicative property of equality. Multiply each side by -1/3.

Without an equality sign it is not an equation
