- That's a good question. If there are letters in an expression, known as variables, we have to simplify that expression.
- Hey John, there's letters in this equation. How do I solve it?
- First, if there are any parenthesis, we have to multiply the value outside of the parenthesis amongst the values or variables inside the parenthesis. For example, if it says 4(x+6), we would multiply 4 by x then multiply 4 to 6 so that simplifies to 4x+24.
- How do we do that?
- For example, if the expression is 4(x+6) + 2(x+5) you'd distribute which would leave you with (4x+24) + (2x+10). Here is where we combine like terms.
- What happens after that?
- No you cannot. Like terms is , for example, two values with x, or two values without a variable. {Keep in mind variables do not have to be x they can be any letter}. So, from there you add 2x to 4x then add 24 to 10 which leaves you with a final simplified expression of 6x+34.
- Before you do that, I have a question, can you add a variable to a normal number?
- Of course!
- Thank you so much for your help!
