In this problem, we're trying to solve the equation, provide the answers, and then checker answer.
00:05
So for this one, we're given that 5x plus 60 is equal to 2x plus 90.
00:09
Now, the order that we do, this could be different, but the first thing i would start with would be to subtract 2x from both sides.
00:15
So this is the given piece of information.
00:17
I'm going to go ahead and subtract, and i would get 3x plus 60 is equal to 90.
00:24
So the reason for each step, for this step here, would be our subtraction, property of equality.
00:30
And i'm going to abbreviate that as p -o -e.
00:34
So then i have 3x plus 60 equals 90.
00:37
My next piece that i'm going to do is, again, to isolate the variable, and i subtract the 60.
00:44
So once again, this is our subtraction property of equality.
00:50
Okay.
00:50
And this process here is isolating variable.
00:56
So my result for this, when i combine those together, is 3x is equal to 30...
