This problem, we're being asked to simplify the given expression.
00:03
Remember, when you simplify expressions, the first thing you need to do is remove your parentheses.
00:08
Well, in front of that first preemphasy is a minus sign.
00:11
So we need to distribute that to both terms.
00:14
Well, when you distribute a minus sign, it changes the sign of both those terms.
00:18
So in other words, the positive 2y will become negative 2y, and the positive 3 will become negative 3.
00:24
And then we're just going to bring down that first term 8y and the last term minus 19.
00:30
Now that we've removed parentheses, we just need to go ahead and combine our light terms...
