18x + 2x + 1=32 -1 18x + 2x=31 And then what?

DerKrebs [107]

Let's look at the equation we have.
18x + 2x = 31

The first step would be to combine like terms. Ex: 18x and 2x
18x + 2x = 31
20x = 31

Now, to isolate the x, you would divide both sides by 20.
20x = 31
x = 1.55

x = 1.55

I hope this helps!

The first week she measured 3 3/4 inches of snow
The second week she measured twice as much snow, and the third week she measured half as much snow as the first week
It did not snow at all in the fourth week

We need to find how much snowfall Samantha measured for the entire month
