In this problem, we're going to solve a two -step equation by solving for the variable w.
00:06
And we're going to use two properties in the process, the addition property of equality and the division property of equality.
00:14
So let's go ahead and start by solving for four ninth, w first.
00:18
And we see this minus 11 here.
00:20
We want to get rid of that minus 11.
00:22
And so we have to do the opposite and add 11.
00:25
Now we've got to do it to both sides because of the addition property of equality to keep the equation back.
00:31
Now the minus 11 and the plus 11 make zero.
00:34
They cancel out.
00:35
We're left with four ninth w equals one plus that 11 is 12.
00:41
Now to finish this we say four nines times w and since this multiplication to get rid of that four nines we have to divide by four nints on both sides...
