If I was asked to think of a number and multiply it by 2,I could write this algebraically as 2x. Write the following algebraically, using x as your unknown. "I think of a number , take away 4 and multiply the result by 3."

## Step 1:The first part of the sentence, "think of a number," suggests that we need to use an unknown, which we will denote as .## Step 2:The next part of the sentence, "take away 4," means we need to subtract 4 from our unknown. This gives us the expression .## Step 3:The final part of the sentence, "and multiply the result by 3," means we need to multiply the result of by 3. This gives us the final expression \( 3(x - 4) \).
