Answer:
x = 5
Step-by-step explanation:
6x - 3 = 3x + 12
-3x -3x
_____________
3x - 3 = 12
+3 +3
_____________
3x = 15
15 divided by 3 = 5
x = 5
You can double check this by replacing x with (5)
If it is right both sides should equal the same
6(5) - 3 = 3(5) + 12
30 - 3 = 15 + 12
27 = 27
This would prove that x = 5

Answer:
$18.00
Step-by-step explanation:
Start by working out 10%, that's easy:
15 ÷ 10 = 1.5
That means a 10% tip would be $1.50, so a 20% tip would be twice that amount:
1.50 x 2 = 3
A 20% tip is $3.00, and added on to the original $15.00, the total is $18.00
