i need help with adding and subtracting like terms .
example 16b,-11b,-2b,3b
The commas make no sense in an algebra statement.
If you want to combine say this:
-23a + 34b -15b + 3a
gather..
a(-23+3) + b(34-15)
add
a(-20)+b(19)
-20a+19b
example 16b,-11b,-2b,3b
If you want to combine say this:
-23a + 34b -15b + 3a
gather..
a(-23+3) + b(34-15)
add
a(-20)+b(19)
-20a+19b
