We can use a variable to represent an unknown number.
2/3x+4=7
Practice makes perfect
When translating a verbal phrase into an algebraic equation, first take note of where the equals sign should be placed. In a verbal description of an algebraic statement, "is" or "is equal to" tells us where an equals sign is located.
... = ...
The key word to note on the left-hand side of the equals sign is " plus." This indicates that we are adding two terms.
... + ... = ...
We are finding "two-thirds a number plus 4." Recall that we can use variables to represent unknown numbers. Let's use x to represent " a number."
2/3 x + 4 = ...
Finally, we will complete the equation with the integer 7 on the right-hand side of the equals sign.
Two-thirds a number plus 4 is 7.
2/3 x + 4 = 7
