Answer:
x = or
Step-by-step explanation:
First, combine like terms. Like terms are terms with the same amount of the same variable.
(2x + 3x) - 7 = 42
5x - 7 = 42
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& roots)
Multiplications
Divisions
Additions
Subtractions
~
First, add 7 to both sides of the equation:
5x - 7 (+ 7) = 42 (+ 7)
5x = 42 + 7
5x = 49
Next, divide 5 from both sides of the equation:
(5x)/5 = (49)/5
x = 49/5
x = 9.8
Given:
Five and one half of 2 and one third.
To find:
The number for the given statement.
Solution:
Five and one half =
2 and one third =
The given statement is five and one half of 2 and one third.
Here, the word "of" is used for multiplication.
So, the expression for the given statement is:
Therefore, the required number is .
