Q & A

What is the first step in solving algebraic addition problems?

The first step is to group similar variables together, making it easier to combine like terms.

In the first example, how do you handle the terms with variable A?

In the first example, the terms with variable A, 7A and 8A, are combined to give 15A.

What happens when you combine 4B and -6B in the first example?

When you combine 4B and -6B, you get -2B.

What is the result of simplifying the first algebraic expression, 7A + 4B + 8A - 6B?

The result of simplifying the expression is 15A - 2B.

How do you approach solving the second example, 15A + 7B - 5C - 11A - 12B + 13D?

In the second example, you group similar variables together, combining the A terms (15A and -11A), B terms (7B and -12B), and so on, before simplifying them.

What is the result when combining 15A and -11A in the second example?

Combining 15A and -11A gives 4A.

After simplifying the second example, what is the result for the B terms?

After simplifying the B terms, 7B and -12B, the result is -5B.

In the second example, how are the terms with C and D handled?

In the second example, the term -5C does not have a matching variable, so it remains as -5C, and the term 13D does not have any other D terms, so it remains as +13D.

How is the expression -3Y - 8Y simplified in the third example?

In the third example, -3Y and -8Y are combined to give -11Y.

What is the final result of simplifying the third example, 3Y + 4X - 6 + 7X - 8Y + 10?

The final result of simplifying the third example is -11Y + 11X + 4.

How do you combine the terms in the fourth example, A + 2B - C + 5A - 4B + 4C?

In the fourth example, you combine the A terms (A and 5A), the B terms (2B and -4B), and the C terms (-C and 4C) before simplifying.

What is the result after simplifying the terms in the fourth example?

After simplifying, the result is 6A - 2B + 3C.
