Example Question #51 : How To Find The Solution To An Equation
Find the difference.
When substracting and , a trick is to pretend that the numbers are actually and You can save the for the end.
Apply the that you were saving from the beginning.
This gives you .
Example Question #51 : Equations
If , what number does stand for?
While is an unfamiliar symbol, just remember that any odd symbols are the equivalent of an unknown variable like or .
To solve this problem, the fastest approach is to plug the various answer choices in as .
When plugging in , this is what happens:
The number is the solution to the equation, so is the correct answer. Plugging in any other number will result in a false result.
Example Question #53 : How To Find The Solution To An Equation
Leila ordered pizzas. Each pizza has slices. If represents the total slices of pizza, which equation would reflect how many slices of pizza Leila ordered?
This is essentially a multiplication-based word problem. If Leila ordered pizzas and each pizza has slices, then to determine the total number of pizza slices, it would be best to multiply . This results in , the total slices of pizza.
Example Question #54 : How To Find The Solution To An Equation
What is the value of the expression ?
This question will require the use of order of operations: PEMDAS (parentheses, exponents, multiply, divide, add, subtract).
When dealing with parentheses, multiplication, subtraction and addition, it is important to first address the parentheses.
Looking at this part of the expression, multiplication is carried out first.
Finally, subtract within the parentheses. The value of the parenthetical expression is .
Next, the addition is carried out:
This results in , the correct answer.

Example Question #59 : How To Find The Solution To An Equation
What is the value of in the equation below?
To solve, you will need to divide both sides of the equation by 5.
The 5 cancels on the left side.
Divide to simplify.
Example Question #52 : Equations
Brian brought a box of 50 chocolates to class. The teacher did not eat any of the chocolate, but his friends ate a total of 12 pieces. How many pieces of chocolate remain uneaten?
Cannot be determined
This question gives extra information about the teacher that is not necessary to solve the problem.
We know that there are originally 50 pieces of chocolate, and that 12 pieces are eaten. Subtract to find the remaining amount of chocolate.
