First, you combine like terms: x+3x=4x: 12+4x=18-2x
Second, you add the 2x to each side (inverse operation): 12+6x=18
Third, you subtract 12 from 18 to cancel out the 12 (inverse operation): 6x=6
Fourth, you divide each side by 6 to find the value of x
The answer is x=1
To find the tip of the bill. You will need to find how much of $86.40 is 20%. In this question, they're asking how much is the tip, not how much will the final price be.
When you multiply a percentage you move the decimal point 2 times to the left: 20. → .20
You would multiply $86.40 by .20
When you solve it 86.40 × .20 = 17.28
$17.28 is 20% of $86.40
$17.28 will be the amount he got for his tip.
