Use the phrase pemdas
it shows the order you solve. parenthesis, exponents, multiplication, division, addition, and then subtraction. ask me if you need any other help!
Answer:
4xyz
Step-by-step explanation:
4 goes into all the numbers and the lowest exponent for each term is just 1.
To simplify this, we need to do PEMDAS (parenthesis then exponents, then multiplication and division, then addition and subtraction). Here, we can't combine any like terms in the parenthesis. Since there's no exponents, that means that the next step is to do multiplication. This gives us:
3 - 15y - 21 + 2y - 6
Now we can combine like terms.
(-15y + 2y) + (3 - 21 - 6)
-13y - 24
