PLEAS HE 1. When writing a linear equation for a word problem, what are some things to keep in mind or some keywords to watch out for? What do those keywords mean/ why should you watch out for those things?

read the problem very well

Step-by-step explanation:

Also watch out for these

SUM OF AND

Underline the words before and after AND when it corresponds to the leading keyword SUM OF.

the sum of five and a number

2. Circle the leading keyword and indicate the corresponding AND that it defines.



3. Translate each underlined expression and replace AND with a plus sign.

The expression translates to 5 + x.

TOTAL OF AND

The keyword TOTAL OF is a leading keyword that defines AND, so underline the words before and after AND: “a number” and “negative three.”

the total of a number and negative three

2. Circle the leading keyword and indicate the corresponding AND that it defines.



3. Translate each underlined expression and replace AND with a plus sign.

The expression translates to x + −3.

Ps. The AND keyword translates to mean “plus” because the leading keyword is SUM OF. With other leading keywords (discussed in the following sections), AND can mean other things. Also notice that you do not simplify the expression and get “3” for the answer because you are just translating words into symbols and not performing the math.

Two other keywords on the addition keyword list, PLUS and INCREASED BY, can be correctly translated by the direct translation strategy. In the direct translation strategy, you translate each word into its corresponding algebraic symbol, one at a time, in the same order as written

u welcome

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
