The word equals divides the statement into what should be on the left-hand side and what should be on the right-hand side of the equation.
y=3x
Practice makes perfect
We have been given a statement and we need to translate it into an equation.
The output is three times the input.
Every equation has an equals sign and values or expressions on either side of it. Key words and phrases such as is,is equal to, and equals tell us about the placement of the equals sign.
The output isthree times the input.
⇕
The output
=
three times the input.
On the left-hand side we have one key word, output. This word represents the variable y.
The output → y
On the right-hand side we have two key words, times and input. The word input represents the variable x. Times indicates the operation that will be used in our equation. In our case, it will be the multiplication.
three times the input
3 x
Putting these sides together, we have a complete equation.
y = 3 x
