Question

how do you simply an algerbratic expression such as -4 (2r-2) +15r-18

Answer 1

opps i ment simplifly

Answer 2

First, you would want to distribute the -4 to the (2r -2) which is 8-8r.
So now we have, 8-8r + 15r - 18.
We can combine the two "r" terms. 15 - 8 is 7.
8 +7r - 18.
Then we can combine the two constant terms, 8 and -18. 8 - 18 is -10.
Then, you have 7r - 10, which is completely simplified.
