That expression can be simplified by combining like terms.
Like terms are terms that have the same variable(s) and the same exponent(s).
The like terms are 7x and 9x.
You can combine like terms by adding the coefficients (the number in front of the exponent) together and then tacking on the variable at the end.
7x + 9x = 16x
Add 16x back to the term that can't be combined (-8y), and the simplified expression is 16x - 8y
U have to write the passage then I can answet
Can you explain further than the question?
Give me that pencil on the floor please.
(Significa: Dame esa lápiz en el suelo por favor.)
