Solve the equation using inverse operations.
2 + x3 =18

Step-by-step explanation:

Isolate x on one side of the equation.

2+x3=18

2+x*3=18

2+x*3-2=18-2 (First, subtract 2 from both sides.)

18-2 (Solve.)

18-2=16

x*3=16

x*3/3=16/3 (Then, divide by 3 from both sides.)

16/3=5.33

x=16/3=5.33

In conclusion, the final answer is x=16/3=5.33.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
