Problem 51, we are solving for x.
00:04
So starting with part a, we got 2x plus 5 equals 41.
00:13
So we want to isolate x on the left side and the constants on the right side.
00:19
Okay, so in order to get rid of this 5 first, we want to subtract 5 from both sides.
00:26
Okay so that cancels out this five because five minus five is zero and then we're going to be left with two x on the left side and 41 minus five on the right side so 41 minus five is 36 so now in order to isolate x on the left side we want to divide two x by two okay so dividing it by two cancels that coefficient, so now we're left with x.
01:05
And x equals 36 divided by 2, which is 18.
01:11
So that's part a.
01:13
Part b now.
01:16
We got 5x divided by 3 equals 40.
01:22
Okay.
01:23
So again, we're isolating x on the left side and all the constants on the right side...
