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 words to note on the left-hand side of the equals sign are " increased by." This indicates that we are adding two terms. ... + ... = ... We are finding " a number increased by 10." Recall that we can use variables to represent unknown numbers. Let's use x to represent " a number." x + 10 = ... Finally, we will complete the equation with the integer 114 on the right-hand side of the equals sign. A number increased by 10 is 114. x + 10 = 114
