The word is divides the sentence into what should be on the left-hand side and what should be on the right-hand side of the equation.
Equation: x+5=- 4 Solution: x=- 9
Practice makes perfect
We want to rewrite the word sentence as an equation and then solve it. We can do each of these things one at a time.
Equation
Let's consider the given word sentence!
5 more than a number x is - 4.
Every equation has an equals sign and values or expressions on either side of it. Key phrases, such as is,is equal to, and equals tell us about the placement of the equals sign.
5more than a numberx is - 4
⇕
5more than a numberx = - 4
On the left-hand side we have one key word, more than. These words tell us the operation that will be used in our equation. More than indicates addition.
5 more than a numberx
x + 5
On the right-hand side, there is only a constant. Putting these sides together, we have a complete equation.
x + 5 = - 4
