How do you simplify algebraic expressions?

Answer 1

You must combine like terms. Then, if you can, simplify it further.

9x+67+34+2x+16xy


First, you do 9x+2x


Now the expression is:
11x+67+34+16xy


now do 67+34


11x+101+16xy


There is no more like terms to simplify so 11x+101+16xy is your simplified expression.

Answer 2

Here's your sentence 2 (3+x) + x (1-4x) + 5

1. Clear the Parentheses

6 + 2x + x - 4x2 + 5

2.Combine like terms by adding coefficients

6+3x-4x2+5

3. Combine the constans

11+3x-4x2

TA DA!!!! I'm only 15 so i hope i helped :D
