The answer is....... 1. read the problem 2. determine the unknowns and represent them 3. write an equation 4. solve the equation 5. answer the question
10n - 24 = 8n + 64 n = 44
15
t + 9 = 54
You have to give me a mathematical operator before 28 for me to correctly answer this question.
By including the + or - signs in the question
you have to write down the equation first so people can answer it
The answer is....... 1. read the problem 2. determine the unknowns and represent them 3. write an equation 4. solve the equation 5. answer the question
You have to decide what the meaning of the equation will be.
CH3CHO+HCl
That IS the equation. You may want to write with the equal sign: 6p = 24
-- take two quantities that are equal to each other -- write them both on the same line, with an "equals" sign between them ( = ) You now have an equation.
1-37
an equal sign
-9p - 15 = 93
This is the picture.
