Final answer:
To translate the sentence 'Two times the sum of a number and 9 equals 4' into an equation, we use the variable w for the unknown number and follow the steps to solve for w.
Step-by-step explanation:
To translate the sentence into an equation, you can use the variable w to represent the unknown number. The sentence 'Two times the sum of a number and 9 equals 4' can be written as:
2(w + 9) = 4
By distributing the 2, the equation becomes:
2w + 18 = 4
Subtracting 18 from both sides, we get:
2w = -14
Finally, dividing both sides by 2, we find:
w = -7
