an equation with more than one operation
Parentheses in an equation tell you that you must perform that operation before any other operations, regardless of what operation that may be.
You need to isolate the variable you want to solve for, on one side of the equation. This involves getting rid of everything else. Note that what you do on one side of the equation, you also have to do on the other side. "Getting rid" of everything else basically means doing the inverse of the operation shown. Example: 2x + 3 = 21 You might start by getting rid of the 3. For this, you subtract 3 on both sides. Subtracting 3 is the inverse of the operation shown in the equation, adding 3. 2x + 3 - 3 = 21 - 3 2x = 18 Next, you get rid of the 2. Once again, since in the equation there is a multiplication by 2, you divide by 2 - the inverse operation. In this case, you divide by 2 on each side: 2x/2 = 18/2 (2/2)x = 18/2 x = 9
You cannot write the quotient itself as an equation, but you can express a division operation and use an equation to express that the result of this operation (the quotient) is a specific value. For example, 16/8 =2.
-26
It means the operation that is shown.
an equation with more than one operation
To solve an equation it is sometimes helpful to do what to the original operation?
The equation remains in 'balance'
The equation remains in 'balance'
Reactants are to the left in a chemical equation.
That must depend on the equation that has not been shown
Operation means that going from the left to the right of your equation, multiplication and division must always be done first before doing addition and subtraction
Parentheses in an equation tell you that you must perform that operation before any other operations, regardless of what operation that may be.
murder the person...operation done
These are reactants and products.
The substance shown on the right side of a chemical equation is called the product. It is the result of a chemical reaction between the reactants on the left side of the equation.
