Example Question #111 : Equations
Solve when
To solve, insert for each variable in the equation.
Using the Order of Operations, PEMDAS, solve the equation. PEMDAS stands for parentheses, exponents, multiplication/division, addition/subtraction. Remember the exponent tells you how many times to multiply the number by itself.
The subtraction of a negative is the same as adding a positive.
Example Question #116 : How To Find The Solution To An Equation
What is the value of in the following equation?
To solve:
First distribute the to the terms inside the parentheses, and then solve using the Order of Operations or PEMDAS (Parentheses, Exponents. Multiplication/Division, Addition/Subtraction):
is the correct answer.
Example Question #111 : How To Find The Solution To An Equation
If , which of the following number sentences are true?
Replace the variable with . Then solve using order of operation (PEMDAS).
Example Question #118 : How To Find The Solution To An Equation
Solve for x in the following equation:
To solve for x in this equation, we must get x to stand alone or get x by itself.
In the equation
to get x by itself, we must cancel out the 2 next to it. To cancel it out, we will divide by 2. If we divide on the left side, we must divide on the right. So,
Therefore, after getting x to stand alone, we can see that .
Example Question #119 : How To Find The Solution To An Equation
Solve for a in the following equation:
To solve for a, we want to get a to stand alone or be by itself. To do that, in the equation
we need to cancel out the 5. In this case, we are subtracting 5 on the left side. To cancel it out, we need to add 5. If we add 5 to the left side, we need to add 5 to the right side. So we get
Therefore, if we solve for a in the equation, we get .
